Adafruit DC & Stepper Motor HAT for Raspberry Pi

Adafruit DC & Stepper Motor HAT for Raspberry Pi info

Let your robotic dreams come true with Adafruit DC & Stepper Motor HAT for Raspberry Pi. 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, a fully-dedicated PWM driver chip is added 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.

In fact, you can even stack multiple Adafruit DC & Stepper Motor HAT for Raspberry Pis, up to 32 of them, for controlling up to 64 stepper motors or 128 DC motors (or a mix of the two) - just remember to purchase and solder in a stacking header instead of the one we include.

Motors are controlled by TB6612 MOSFET drivers with 1.2A per channel and 3A peak current capability and there are built-in flyback diodes as well. To the little space left, a polarity protection FET on the power pins and a bit of prototyping area are added.

Adafruit DC & Stepper Motor HAT for Raspberry Pi comes with an assembled & tested HAT, terminal blocks, and 2x20 plain header. Some soldering is required to assemble the headers on. Stacking header not included, but we sell them in the shop so if you want to stack HATs, please pick one up at the same time.

Adafruit DC & Stepper Motor HAT for Raspberry Pi - General Specifications

• 4 H-Bridges: TB6612 chipset
• 1.2A per bridge (3A peak)
• Thermal shutdown protection,
• Internal kickback protection diodes
• Can run motors on 4.5VDC to 13.5VDC.
• Up to 4 bi-directional 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 model A+, B+, or Pi 2
• Can be used with a model A or B if you purchase a 2x13 extra-tall header and solder that instead of the 2x20
