1. Connect TP1/TP2, Gnd/Reset cables to the signal routing board and checked that the reset button works OK, and the DVM displays TP1/TP2 voltage 5.06V (PSU side is 5.3V, but dropped 0.24V by the long cable and perhaps also RPi circuit traces.
2. RPi 5V0 and 3V3 connected to the signal routing board. 5V0 supplies the DVM and also LED indicator LED. 3V3 powers the LED indicator LED.
Next step is to test the GPIO things - LED, buzzer, and button.
Jogging time.
