Hardware: redbearlabs Nano V2 (see pinout below) Programmer: DAPLink v1.5 supplied by redbear IDE: Arduino with the redbearlab nano 2 board package
The schematic can be found here: github.com/.../Nano V2.0 SCH 20161102.pdf
Specifically, I've tried to use D0, D1, D2 and D3 as outputs without any success (D4 and D5 work well). I have a feeling that I can't use these pins as they are being used for serial communication.
Thanks!
