Free Express Shipping on Orders over $200!



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 SeeedStudio BeagleBone Green or BeagleBone Black 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.
