Banana Pi BPI bit robot Extension for Smart Cars and Robots PCA9685

Banana Pi bit:robot expansion board has been designed to facilitate developers working on robots and smart cars. In addition to the conventional I/O functionality, the BPI bit-robot extension supports advanced bit-architecture. The hardware is compatible with 12V/2A DC power supply (if servo motor or DC motor is connected). But if DC motor or servo motor is not connected, then the BPI bit-robot extension also supports 5V/2A MicroUSB power supply.
