This circuit uses the DRV8833 and allows up to 2 DC motors or 1 stepper motor to be controlled by a microprocessor. This is useful as a microcontroller cannot, on its own, output enough power to drive most motors. Using this board you can control motor with digital outputs (two per motor) from your microcontroller while powering it separately from a suitable power source.The motor driver operates off a wide power supply (2.7-10.8V) and can provide up to 1.5A per output or 3A if the motor is connected to both outputs in parallel. Depending upon the state of the two control lines, the motor can be controlled to coast, reverse, go forward & brake.
The board can easily be connected to a microcontroller and will operate at 3V or 5V.
Features:
- Drives two motors or one stepper motor.
- 1.5A per channel.
Contents:
- 1 x Motor/Stepper Driver Breakout Board.
Possible applications include:
- Robotics.
Dimensions:
- Length: 38mm.
- Width: 28mm.
- Height: 3mm.
Connections:
- Vcc: Supply Voltage (0-10.8V)
- GND: Ground
- nSLEEP: Sleep mode pin (Bringing this low enters the device into sleep mode)
- xINx: Control, logic inputs (AIN1, AIN2, BIN1, BIN2)
- xOUTx: Motor outputs (AOUT1, AOUT2, BOUT1, BOUT2)

Yes you can use this along with the BBC micro:bit to drive motors. You would still need to use the edge connector breakout board to allow you to use the correct pins. https://www.kitronik.co.uk/5601-edge-connector-breakout-board.html

0voteA: Hi Christian, Unfortunately we don’t have any documentation for using a micro:bit with this board. However you should be able to keep the set up similar to how it is with Arduino and drop the micro:bit in its place with an edge connector to break the pins out further. As an example you could use pins 12 & 8 for one of the input pairs and pins 16 & 0 for the second input pair.Posted by on Monday, 24 July 2017
