AVR-ISP500-ISO is a professional, fast and reliable USB AVR programmer. It has two modes of operation: STK500v2-compatible USB programmer and command logging state. In STK500v2 mode it works directly with AVR studio and Atmel studio. Alternatively, the STK500v2 protocol is supported in AVRDude.

AVR-ISP500-ISO has an internal flash of 2MB and can store the last command and code that you executed in AVR studio, amd then you can execute it again with a single button push. This means that once you load the code in the internal flash, you can program targets quickly with the same binary code by a single button press.

AVR-ISP500-ISO is galvanically isolated from the target with 1000VDC isolation, which means you can use it with targets working on high voltage without the risk of damaging your computer (if the target is faulty) OR damaging your target (if the computer USB port is faulty).


  • Connects to PC via Full speed USB 2.0
  • 1000VDC galvano isolation
  • STK500v2 protocol mode
  • Internal flash of 2 MB for stand-alone programming with single button press
  • Two ICSP connectors - Atmel's 10 pin (2x5) ICSP and 6 pin (2x3) ICSP connectors
  • Does not require external power supply - it gets powered by the USB
  • Dimensions (45x30)mm ~ (1.7x1.2)" + 20cm ~ 8" cable




  • I can't get this programmer working with Arduino IDE. What should I do?
  • Follow the installation algorithm below. It was tested and confirmed working with Windows 10 and Arduino 1.6.7:

    1. Plug AVR-ISP500-ISO to the computer via USB cable with a USB type B connector.

    2. If you have a newer version of Windows the drivers would install automatically. If they do not install automatically, download the drivers from the links above and manually point the installer to the drivers. If the installer refuses to install the drivers due to the lack of signature - make sure to disable the "Driver Signature Enforcement" and then try to install the drivers again. Upon a successful installation a new COM port would appear in "Windows Device Manager".

    3. Before launching Arduino IDE you need to add a configuration for the Olimex programmer. It is simple – navigate to *\arduino-1.6.7\hardware\arduino\avr\ and open the file programmers.txt for editing. At the end of the file add the following:

    olimexisp.name=Olimex AVR-ISP500-ISO

    4. Launch Arduino IDE and select Tools –> Programmer –> “Olimex AVR-ISP500-ISO”; also select the COM port of the programmer as listed in “Windows Device Manager”(!) after a succesfull driver install

    5. Remember to click Sketch –> Upload using programmer – if you just click “Upload” then Arduino IDE would attempt to upload via the USB.
