Drive your next robot or motion project with the Adafruit DC + Stepper Motor HAT! Control 4 DC or 2 stepper motors via I2C with powerful TB6612 drivers, built-in protection, and no soldering required — plug in and go!
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.
Raspberry Pi and motors are not included. Works with any and all Raspberry Pi computers with 2x20 connection port.
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 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.
Motors are controlled by TB6612 MOSFET drivers with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time), a big improvement over L293D drivers and there are built-in flyback diodes as well.
We even had a little space so we added a polarity protection FET on the power pins and a bit of prototyping area. And the HAT is assembled and tested here at Adafruit with the 2x20 connector and terminal blocks already soldered on, so this is a plug-and-play, no soldering required motor control kit!
Comes with an assembled & tested HAT, with terminal blocks already soldered on, and 2x20 lifter header so it will clear the ports on a Raspberry Pi computer. No soldering required!
Please note: Raspberry Pi, motors, and battery pack are not included, and the terminal blocks included with your product may vary in colour.
Features
4 H-Bridges: TB6612 chipset provides 1.2A per bridge with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC.
Up to 4 bidirectional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.
Big terminal block connectors to easily hook up wires (18-26AWG) and power
Polarity-protected 2-pin terminal block and jumper to connect external 5-12VDC power
Works best with Raspberry Pi's with 2x20 connectors: A+, B+, Pi 2, Pi 3 Pi 4, Pi 5, Pi Zero, etc....but can be used with first-generation model A or B if you purchase a 2x13 extra-tall header and solder that instead of the 2x20
Install the easy-to-use Python library, check out the examples, and you're ready to go!
