PCA9685 Servo Driver

The Quad SMARS uses a PCA9685 servo driver board to power and control the 8x servos (legs and feet). Some version of this board come pre-assembled; the servo driver cover doesn't have a hole for the large capacitor, but you can safely de-solder this (or just cut the legs off). You may also need to bend the header pins to the upright position to fit in the servo driver cover.
