I have everything I need to add more USBs and a fan to the CM3 but as long as I was taking it back apart, I'd like to add a second set of trigger buttons and a hotkey button through the unused GPIO pins. As far as I can tell, I just wire a button between an unused pin and ground. **Please correct me if I'm wrong** The part I need help with is coding. I am not software savvy at all. Could someone please provide instructions on modifying the software to add three more buttons? Also, if there are preferred pins to wire to. Thank you so much! I will post pictures of the final build.
