adafruit dc stepper motor hat on fritzing

Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution).

4 H-Bridges: TB6612 chipset provides 1.2A per bridge with thermal shutdown protection, internal kickback protection diodes.

The Bonnet is fully assembled and tested at Adafruit so all you have to do is plug it right onto your Raspberry Pi.

A chunky polarity protection FET will protect your precious Pi and Bonnet from accidental mis-wiring of the battery/power port. 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. In fact, you can even stack multiple Motor Bonnets, 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 2x20 stacking headers. 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.
