XinaBox OC05

The OC05 xChip is an 8-channel servo motor driver. It is based on the popular PCA9685 manufactured by NXP Semiconductor. It is 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.

Please note, OC05 and all other xChips is currently only supported in Zerynth Studio with XinaBox CW02. Review the Quick Start guide for interfacing xChips.
