Hello everybody.

I was following the instruction manual of the MOD-IO2, but I can't get pass the powering up section.
I am using a enercell power adapter (12V @ 1A).
Is there something i'm missing? Should it be connected to the board for the LED to turn on?
Thanks for any help you can provide.



It did just work for me. I connected a 12 V adapter and the power LED came on. Did you check the polarity of the power supply and if it is working at all?


Hello Bernd,

I just checked the power supply with a multimeter and it seems ok.


Hey agcr,

Is it possible to upload the latest firmware to the MOD-IO2. You might have received a board with the older firmware (v1). The latest one is available here:

Hi Lub,

Thanks for your reply.
Can you provide me with some instructions on how to do it. I checked the zip file but there were none.
