Connect the servos using the diagram below as a guide. The PCA9685 has 16 ports for connecting to servos, the Quad only uses 8 of these.
The table below shows the wiring for each limb, leg and foot:
|Servo #||Side||Front / Back||Type|
Next, the PCA9685 board needs to be wired to the Raspberry Pi Zero. There are 5 pins that we need to connect:
|PCA9685 Pin||Description||To Raspberry Pi Pin|
Please note the power supplied from the Raspberry Pi Zero to the Servos may not be suffient - you may need to attach a larger power supply (battery) to the Power + and GND at the top of the PCA9864 board.
