control motor direction and speed. This chip handles all the motor and speed controls over I2C. Only two GPIO 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 Motor HATs, up to 32 of them, for controlling up to 64 stepper motors or 128 DC
motors - just remember to purchase and solder in a stacking header instead of the one we include.
Motors are controlled TB6612 MOSFET driver: with 1.2A per channel current capability (20ms long bursts of 3A peak),
a big improvement over L293D drivers and there are built-in flyback diodes as well.
If connecting the Hat off-the Pi via jumpers, you will need to connect GND and 3.3v in addition to SDA and
SCL.
