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.

LED Wiring

The LED is wired to Pin 1 and 9 on the PiTFT.
