All orders must be placed through our website

Please note: OLIMEX Ltd does not consider the receipt of a Purchase Order document as valid submission of an order if this order is not placed through our web site this order do not exist for us. You can't place an order with us through faxes, emails, phone calls, so please don't do this.

There are no minimum orders.

Please Note: It may not be possible to cancel your order once it has been placed. To avoid any trouble, please make sure you want everything in your cart before clicking 'Submit Order'.

If you entered correct e-mail when filling your order you will receive e-mail confirmation if you complete your order online.

You can check your order status from this page:


All prices on our web are in EURO currency. For customers from Bulgaria (when select Bulgaria as country in CHECKOUT page), prices are shown in Bulgarian Leva and payment is effected in BGN.

All price discounts are generated automatically at the time when you enter your order depend on the quantity you enter, we do not offer any other discounts than these on our web.


Please do not ask us to make manual quotations/offers for you - all our offers are generated automatically - just add the items you are interested to your basket, CHEKOUT and select your country then select your preferred transport option - you will see how much total cost is and no need to ask us for this. Note that even if the orders are submitted they need to be paid to be processed. Orders which are submitted but not paid are ignored, so do not worry that you "place" order on our site. If the order is not paid it will not be proceed.

European VAT Registration and Exemption

If you're a Non-Bulgarian VAT registered business based within the EU economic area you can avoid paying VAT on your purchase with us by taking the following steps:

1. Enter your VALID VAT-ID when you place your order (the VAT-ID field will appear only when you select country within EU economic area).

2. DO NOT place your order until you see the VAT at checkout go to zero.

Requests to refund VAT on purchases made where there is a valid VAT number, but where the VAT-ID was not entered at the time of the purchase and the order is paid and shipped with invoice including VAT, will incur a EUR 30 admin fee to action the refund.

Please be very careful when you enter your VAT-ID, we recommend you to check if it is valid VAT-ID first at VIAS WEB site as when you enter your order we do not do real time check due to the permanent problems with VIES servers they quite often timeout or are down. We check these VAT-IDs before shipping though, so entering incorrect VAT-ID will lead to significant delay in your order processing and it may be hold for several days untill we collect the not paid VAT 20%, so our advice is to enter only VAT-IDs which first you check on above web site and it confirms them. Some countries like Spain and Italy have "internal" VAT-IDs which are not updated to VIES VAT-ID server, if you have such VAT-ID please do not enter it as it is not valid VAT-ID for EU VAT free purchase.


All orders with us have to be pre-paid. We do not offer any other terms.

CREDIT CARD: We accept Visa, Mastercard, Visa electron and Maestro cards. The card payments are processed online by United Bulgarian Bank card processing. Restrictions for this payment option for some countries exist, if when you select your country this payment option is not listed this means your country is excluded for security reasons. If the order value is above EURO 300 card payment fee will apply.

To protect you from fraud payments with your Visa or MasterCard, we use the best practices recommended by international card organizations:

  • SSL protocol is used to encrypt the connection between our server and the servicing bank and your card info is transmitted secure.
  • The authenticity of your card is verified by introducing security code (CVV2)
  • In addition, to identify you as the cardholder, the payment server of our servicing bank supports the authentication schemes of international card organizations - Verified by VISA and MasterCard SecureCode, in case you have registered to use them.

PAYPAL: PayPal is fast, easy and efficient and allows people who have PayPal accounts to transfer money easily to us. Opening a new account is free. You can pay with your card via paypal also. PayPal has service charge of 5% which will be add to your order value. Note that your payment should be sent in EURO currency, payments sent in other currency than EURO will be refunded back and the order canceled. Also please note that the address you fill in your order and the paypal address should match. If paypal and order addresses do not match your order will be put on hold and not processed.

Please use your order number as a reference for your payment, or we may not be able to identify your funds and process your order. Orders where payment has not been received 15 working days after the order was placed will be cancelled. Please note that bank transfers usually take few business days to move the money from one account to other. We will not ship your order until your payment is verified by our bank. A record of the transaction from your bank is not sufficient to release an order. Due to the high cost of accepting bank trasnfers all orders paid by bank transfer are subject to bank handling fee if your order is below EUR 1000.00; The bank handling fee is EUR 30 if the payment is sent form country outside Europe Union. Please note that all bank transfer fees should be covered by the sender (Detail of charges: OUR).

Usually 90% of the orders which are paid before 10.00 AM Bulgarian local time are shipped the same day and these with payment received after 10.00 AM are shipped the day after we receive the payment, but we say we ship in 3 working days as sometimes there are many orders to process and this require additional time, so please always consider that your order will be shipped in 3 working days, if we ship faster we are sure you will not complain :)

All orders are shipping from Plovdiv, Bulgaria.

Check order status

You can check your order status from this page:

Billing and Shipping

We do not allow billing and shipping addresses in different countries. Please do not try to cheat by entering incorrect addresses for billing if in different country, on such orders the billing info will be deleted automatically.

Shipping invoices

Invoices are generated at the time of shipping. The shipping invoice and notification is sent to e-mail address which is entered when order. If you do not receive shipping notification and invoice check in your SPAM filter or if your e-mail do not block PDF attachments. You can always download your shipping invoice for your current or previous orders at

Broken Items during shipment

Note: claims for broken items can be made only if your shipment was insured. When you have shipment with insurance, please always check the shipment content in the presence of the courier when receive it. If there are broken items make official claim. If you do not make claim and you find items broken later when the courier is not present the courier company may decide that you broke the item after the delivery and not accept the claim. We will need this claim reference to deal with insurer.

Incorrect addresses

Orders which have incorrectly filled addresses usually got non delivered and return back to us. In case of post shipments there are no additional fees for the returns, when parcel returns we just refund the cost of the boards without the shipping charge.

The courier companies are more flexible, but if for some reason the customer didn't provide correct phone or address and is unreacahble there are two options - the parcel to be destroyed or to be returned back. Note that shipping back charges are ALWAYS several times higher than the special shipping charge we have from the couriers because we have special discount only for shipping from Bulgaria, but when the shipment is from another country (return) they bill us on their standard tariff which is in range EUR 80-100.

For the couriers the shipping address must be physical address with someone who is AVAILABLE to sign for the delivery. No POST BOX or address where no one is during the working courier hours. They will not leave it on the address without someone to sign. Also couriers will not deliver to UNIVERISTY addresses where thousands of peoples are located. They will not spend time to look for you in the University just return the parcel.

Shipping options

NOTE: Olimex cannot be held responsible for damaged, lost, or stolen packages for non insured parcels.

If you want to add insurance please check the insurance checkbox on the checkout page.

Note that all times quoted below are for WORKING days and exclude weekend days, also if your country is outside EU there may be additional delays caused by import export procedures and customs clearances.

AIRMAIL: This is not-insured, non-trackable POST service. We allow only orders under EUR 100 to be shipped with this service. Delivery to Europe usually takes 1-2 weeks, outside Europe 2-5 weeks. Once we ship by POST there is no way to track or trace where is your shipment or if it stolen, missing etc. Be careful and use this shipping option on your own risk. If you choose this shipping option, we can't do anything to help you with your parcel once we ship. Orders sent by post will not have a proof of postage. Why I do not have cheap AIRMAIL shipping for my country? Airmail is available for every country, but it's slow service and some people do not want to wait, but just dispute their payments after 1-2 weeks from the shipping, then they receive their parcel for free and forget that they disputed the payment, when the number of such people from given country rises too much, we just disable this shipping option for this country.

DPD CLASSIC: This is Road service very suitable for shipments with higher weight, usually arrives in any European destination for 1 week. All parcels shipped by DPD have automatic Limited insurance for up to 520 EUR per parcel, with online tracking at DPD do not deliver to post boxes.

DHL: This is probably the best option to use as DHL accept parcels up to 17.00 oclock, this means that if you are from EU and place your order even hour before we close there is pretty good chance your parcel to be on your desktop next day in the morning. Good price and very fast service. Our own monitoring show that all parcels we ship with DHL usually are delivered in average 1.5 days worldwide (do not include customs delays), this means large portion of the shipments are delivered next day. By default this is not insured service, online tracking is available at DHL do not deliver to post boxes.

TNT EXPRESS: This is good price and fast service but TNT accepts parcels until 15.00 o'clock so if your order arrives later the shipment will be next day. For most of the Europe destinations and parcels arrive next day or in 2-3 days, but not as fast as DHL for other parts of the world. By default this is not insured service, online tracking is available at TNT do not deliver to post boxes.

FEDEX INTERNATIONAL PRIORITY: This is expensive service but preferred in some parts of the world. By default this is not insured service, online tracking is available at The parcel usually needs 2-4 days to arrive to you. FedEx do not deliver to post boxes.

SPEEDY: This is for shipments only inside Bulgaria, they are express for next day delivery and economy for two days delivery. Note that some remote destinations may take three or more days, reffer to Speedy transit time calculator for this.

SPEEDY FOR GREECE: This is extremly fast service if you live in the bigger cities like Thesaloniki or Athens etc, Speedy usually deliver the parcel to Thessaloniki next day we ship then it's distributed by local Greece courier or post for the remote destinations and islands. There is phone numbers in Greece 0030 2321098003, 2321035735 which you can call and ask info about your parcel as the Speedy tracking works just to Thessaloniki depot :).

SPEEDY FOR ROMANIA: This is extremly fast service if you live in Bucuresti they usually deliver next day we ship, from Bucuresti the parcels are distributed from local courier so in 1 to 3 days the parcel will reach any Romanian destination.

UPS EXPRESS SAVER: Decent service but take parcels only by 12.00 this means that all orders received after 10.00 with UPS shipment will just stay in UPS office until next day, this is why UPS EXPRESS SAVER shipments may arrive next day or max in 2-3 days in Europe and few days more for Rest of the World. By default this service is not insured, online tracking is available at UPS do not deliver to post boxes.

UPS STANDARD: This is road service like DPD but is with better price for small packages 1-3 KG for some destinations. By default this is not insured service, online tracking is available at The parcel usually needs 1 week to arrive to you.

PLEASE NOTE: all transit times above are just based on past experience the courier companies from time to time may deliver for more than the quoted above time. We will not refund your shipping charges if any of the above transport companies fail to meet above quoted delivery times.

Country of Origin

All our boards are produced in our factory in Plovdiv, Bulgaria, European Union.

On our web we sell Integrated Circuits which are made by NXP, TI, Samsung, Hynix, Micron, Allwinner, Espressif which are not manufactured in Bulgaria.

If the customer refuses to pay these extra import charges, the return shipping and any additional fees will be taken out of the cost of the order, with any remaining funds being refunded to the customer.

Please consult with your local import customs authorities about the import duties and taxes you have to pay before ordering.

Note that as written above the courier shipment returns may be several times higher than the special price we have for shipment from Bulgaria, so in some cases the shipping back charge may be higher than the order content in such situation if the customer refuse to accept the parcel and pay the import duties the parcel we will order the courier to distroy the shipment at destination and not deliver back and no refund will be made to the customer.


All goods we sell are new, factory fresh and tested before enter our stock. Only very rarely does an item not function at first use. If this happens, we will do our very best to replace it as long as the below conditions for return are met.
Please check your order as soon as you receive it. Any goods to be replaced must be returned within 7 days.

The warranty covers manufacturing defects and faulty components, please note that warranty do not cover problems due to improper use, over voltage abuse, ESD shock, improper handling etc.


All goods are checked before they are sent out. In the unlikely event that goods are faulty, they must be returned, to OLIMEX at the address listed on your order invoice.

OLIMEX will not accept goods that have clearly been used.

If the goods are found to be in working condition, and the lack of functionality is a result of lack of knowledge on the customers part, no refund will be made, but the goods will be returned to the user at their expense.

All returns must be authorized by an RMA Number. Email for authorization number before shipping back any merchandise. Please include your name, phone number and order number in your email request.

Returns for any unaffected development board, programmer, tools, and cables permitted within 7 days from the date of receipt of merchandise. After such time, all sales are considered final.

Returns of incorrect ordered items are allowed subject to a 10% restocking fee. What is unaffected? If you hooked it to power, you affected it. To be clear, this includes items that have been soldered to, or have had their firmware changed. Because of the nature of the products we deal with (prototyping electronic tools) we cannot allow returns of items that have been programmed, powered up, or otherwise changed post shipment from our warehouse.

All returned merchandise must be in its original mint and clean condition. Returns on damaged, scratched, programmed, burnt, or otherwise 'played with' merchandise will not be accepted.

Boards which are originally shipped by us in ESD antistatic packing, returned back to us not inside ESD protective antistatic packing will be considered with void warranty. We will not repair nor replace such boards.

Long Term Availability

We produce all our boards as long as there is reasonable demand for them and we can source the major components.

Sometimes the number of sold boards per year go below reasonable manufacturing levels, in this case we mark this board as obsolete once it goes out of stock and we have no stock of blank PCBs for it.

Note that obsolete boards could be ordered, in such case contact us and ask for quotation, we will respond with the minimum order quantity to manufacture this board. It usually is about 100 pcs for most of boards.


All OLIMEX products are ROHS and REACH compliant.



OLIMEX tries to support and encourage open source movement and projects, the implementation of these goals though is not easy.

We ran "Free boards for open source initiative" back in 2011 and for nine months we gave away more than 30 different boards and programmers to people who submitted projects to us, promising that they will complete this or that open source project, needless to say 19 months later none of them is complete, the reasons - no time to complete this yet ;)

So obviously give me free board I promise will do this or that do not attract serious people but these who just want to grab free stuff.

Later on we decided to do something else - developers who buy our boards and then do open source project with them to receive discount for their next purchase, this kinda working better than the first initiative, but is so long in time that many developers forget to ask for their discount.

So what we decided to do from now on is to send some of our newly developed boards to people who we see to be active on our forum , to contribute and help others there when they have questions, also the active developers around OLinuXino project always can count on us to receive free boards of all new OLinuXino boards we make. These are people who help with the Linux Kernel, drivers, Linux distributions etc.

Hacker-labs, Hacker-spaces, communities which teach childerns on volunteering basis in Bulgaria and all around the world will always get discount, just contact us and send us your web site and the projects you have been completed and working on, before you make your order so we will assign you special login username and password for ordering with discount.
