Wired Connections
All parts share common ground and voltage. The ground and voltage lines are wired to the 3V and GND pins on the 128x64 OLED breakout. The 128x64 OLED breakout uses a STEMMA QT cable wired into the Doubler FeatherWing. All of the signals from the potentiometers are wired into the Doubler FeatherWing.
