that both will turn on/off at the same time

Instead of 2 DC motors, you could also control a single bi-polar stepper motor (5VDC power) or single uni-polar

stepper motor. You'll use the ground pin for the 5th (and 6th, if it exists) wire of the uni-polar stepper.

Uses the DRV8833 dual H-Bridge motor driver chip (https://adafru.it/Bfk)

The seesaw chip on the Crickit does all the management of these pins so your Feather or CPX does not directly

control them, it must send a message to Crickit. They are on seesaw pins 22 + 23 (motor 1) and 19 + 18 (motor 2)

4 x High Power Drivers

In addition to servos and DC motors, you may find you

want to drive other high-power electronics like relays,

solenoids, powerful LEDs, vibration motors, etc. Some of

these devices are motor-like and need a kick-back

protection diode, so having a proper driver is important

to avoid damage!

This is where you will want to use the high power Drive

terminal block. You get four high current drivers. Each

driver is a 'Darlington' transistor that, when turned on,

connects the output pin to ground.

That's a little different than most other outputs on the

Crickit: The Crickit can only connect/disconnect the

drive pins to Ground! You cannot 'set' the Drive output

to be a high voltage. So, if you're driving a solenoid,

relay, vibration motor, etc. connect one side to the 5V

pin, and the other side to one of the driver pins. You can

connect multiple wires to the 5V pin if necessary.
