MOD-IO2 is a stackable development board which adds RELAYs and GPIOs to any of our development boards with UEXT. If you work with any of our development boards with a UEXT connector and you need more GPIOs and/or RELAY outputs, you can add these by connecting MOD-IO2 to your development board. This board gives you an easy way to interface up to 2 relays and 7 GPIOs. MOD-IO2 is stackable and addressable, what does this mean? It means that these boards can stack together so you can add as many inputs and outputs as you want! E.g. 2-4-6-8 etc.! MOD-IO2 has a CH32V003 microcontroller and the firmware is available for modification.

Product change notice: starting hardware revision C the main chip was changed to CH32V003; the firmware and usage is almost identical and firmware resources and Arudino library and examples had been updated.

FAQ

  • I found a very nice example of MOD-IO2 connected to another board in the internet. It doesn't work despite that I use the same setup as the author. What might be different?
  • There are number of firmware revisions that had been released for MOD-IO2. You should ensure the example you have found used the same firmware revision of MOD-IO2 as the one you have on the module at the moment. Each major firmware revision might use a different board address (for firmware revisions 3, 3.1, 3.02, 4.3, 5 it is the same - 0x21) AND DIFFERENT SET OF COMMANDS. Each firmware has a README file inside the source archive that is available for download. Refer to that README or the user's manual for more information about the firmware.
