Found some generic test rigs we made for small productions back in the day. They are based on a Raspberry Pi 2, and have a variable power supply with current measurement, ARM and AVR programming headers, digital and analog IO, connectors for a 'start' button and pass/fail indicator LEDs, and an RTC (since you won't get internet access in a small Chinese CM, especially in 2016!)
@cibomahto Did you ever have any issues running the RPis on the line? I've been tempted to do this many times, but colleagues have looked down on the Pi as not being "industrial". And some have been burned by flash memory corruption...
