Let your robotic dreams come true with the new DC+Stepper Motor HAT from Adafruit. 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.

Since the Raspberry Pi does not have a lot of PWM pins, we use a '''fully-dedicated PWM driver''' chip onboard to both control motor direction and speed. This chip handles all the motor and speed controls over I2C. Only two GPIO 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.
In fact, '''you can even stack multiple Motor HATs''', up to 32 of them, for controlling up to 64 stepper motors or 128 DC motors - just remember to purchase and solder in a stacking header instead of the one we include.
{{ambox|text=If connecting the Hat off-the Pi via jumpers, you will need to connect GND and 3.3v in addition to SDA and SCL.}}

Motors are controlled TB6612 MOSFET driver: '''with 1.2A per channel current capability''' (20ms long bursts of 3A peak), a big improvement over L293D drivers and there are built-in flyback diodes as well.
