Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or HATs to the same pins. This chip handles all the motor and speed controls over I2C. Since the Raspberry Pi does not have a lot of PWM pins, this uses a fully-dedicated PWM driver chip onboard to both control motor direction and speed. Works with any and all Raspberry Pi computers with 2x20 connection port. Raspberry Pi and motors are not included. Adafruit basically took their super-popular DC+Stepper Motor HAT and squeezed it down and made it fully assembled - plug and play ready to go, no soldering required! This Raspberry Pi add-on is perfect for any motion project as it can drive up to 4 DC or 2 Stepper motors with full PWM speed control. Let your robotic dreams come true with the new DC+Stepper Motor Bonnet from Adafruit.
