Adafruit DC/Stepper Motor Bonnet for Raspberry Pi

Adafruit DC/Stepper Motor Bonnet for Raspberry Pi is an add-on that drives up to four DC or two stepper motors with full PWM speed control. This motor bonnet comes with an onboard fully-dedicated PWM driver chip that controls both motor direction and speed through the I²C interface. The DC/stepper motor bonnet incorporates TB6612 MOSFET drivers with 1.2A current capability per channel and built-in flyback diodes. This motor bonnet is suitable to operate with the Raspberry Pi model Zero, A+, B+, Pi 2, or Pi 3.
