Wired Connections
The diagram above depicts the connections for the PowerBoost 1000C, audio amp, PiTFT, rotary switch, LED and Pi. Use this as a reference for wiring the components. Note, the length of wires and position of components are not exactly how the circuit will be - it’s just a diagram to show connections.
The 3.5" PiTFT connects to the Raspberry Pi's GPIO header. The rotary switch, LED and PowerBoost connect to the GPIO breakout on the 3.5" PiTFT.
