Motor Bridge Cape

The Motor Bridge Cape features bi-directional motor control using two TB6612FNG integrated dual H-bridge, so it can control two stepper motors or four brushed DC motors with 6~15V DC power and about 1A current draw per motor. The cape provides 5V regulated power to BBG or BBB with a max input voltage of 15V. It also has six servo control interface and six expand IO. All the features are provided by the on board STM32F0 coprocessor. The coprocessor can communicate with BeagleBone by I2C or UART interface. Can drive 4 DC Motors or 2 Stepper Motors

Can drive 6 Servos

Mbed Platform

STM32F0 coprocessor

Two TB6612FNG

6 expand IOs

Communicate with BBG by I2C or UART interface

Battery Input Voltage: 6~15V

H-bridge Working Voltage: 6~15V

DC/DC 5V output current: 2A max

3V3 output current: 350mA max

4 H-bridge driver,each rated current:1.2A, peak current:3.2A

6 Servo driver, working voltage: 5V, total current is not more than 1.5A

Input reverse connect protection

Over current protection: 3A one-off quick fuse

It is a demo which we connect Motor Bridge Cape with BBG to drive 1 Stepper Motor, 2 DC Motors and 6 Servos at the same time.
