Adafruit basically took their super-popular DC+Stepper Motor HAT and squeezed it down and made it \u003cstrong\u003efully assembled - plug and play ready to go, no soldering required!\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRaspberry Pi and motors are not included. Works with any and all Raspberry Pi computers with 2x20 connection port.\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eSince the Raspberry Pi does not have a lot of PWM pins, this uses a \u003cstrong\u003efully-dedicated PWM driver chip\u003c\/strong\u003e\u003cstrong\u003e \u003c\/strong\u003eonboard to both control motor direction and speed. This chip handles all the motor and speed controls over I2C. Only two pins (SDA \u0026amp; 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.\u003c\/p\u003e\n\u003cp\u003eIn fact, \u003cstrong\u003eyou can even stack multiple Motor Bonnets\u003c\/strong\u003e, 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.\u003c\/p\u003e\n\u003cp\u003eMotors 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)\u003cstrong\u003e, \u003c\/strong\u003ea big improvement over L293D drivers and there are built-in flyback diodes as well. A chunky polarity protection FET will protect your precious Pi and Bonnet from accidental mis-wiring of the battery\/power port. The Bonnet is fully assembled and tested at Adafruit so all you have to do is plug it right onto your Raspberry Pi.\u003c\/p\u003e\n\u003cp\u003eLets check out these specs again:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e4 H-Bridges: TB6612 chipset provides \u003cstrong\u003e1.2A per bridge\u003c\/strong\u003e with thermal shutdown protection, internal kickback protection diodes.
