Adafruit ADA4280 DC and Stepper Motor HAT for Raspberry Pi

The Adafruit ADA4280 DC and Stepper Motor HAT for Raspberry Pi is the missing link required to let your robotic dreams come true. 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, this HAT uses a fully dedicated PWM driver chip onboard to control both 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.

Scale up your projects further by stacking multiple Motor Bonnets, up to 32 of them, for control of up to 64 stepper motors or 128 DC motors (or a mix of the two) - just remember to purchase 2x20 stacking headers.

Motors are controlled by TB6612 MOSFET drivers with 1.2A per channel current capability, a big improvement over L293D drivers and there are built-in flyback diodes as well. A polarity protection FET will protect your Pi and Bonnet from wiring mix-ups of the battery or power port. The Bonnet is fully assembled and tested at Adafruit prior to shipping, so all you have to do is plug it right onto your Raspberry Pi and get creating.

• 4 H-Bridges: TB6612 chipset provides 1.2A per bridge with thermal shutdown and kickback protection.
• Capable of running motors on 4.5-13.5VDC.
• Up to 4 bi-directional DC motors with individual 8-bit speed selection
• Up to 2 stepper motors with single or 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
• Easy-to-use Python library, check out the examples and you're ready to go!
