Overview
The OC05 xCHIP is a servo motor controller driver that uses the PCA9685 PWM controller as
servo interface supported by a BU33SD5 regulator to drive and accurately control up to 8 servo
motors on a single module and act as system power supply. The module has 8 standard 2.54 mm
(0.1") servo headers, plus 1 standard 2.54 mm (0.1") battery/BEC input header.
