Motor driver
MX1508 dual H-bridge DC motor driver module
Lets a board drive two DC motors forwards, backwards and at the speed you choose.
2Use it
| Pin or leg | What it is for |
|---|---|
| + and - | power for the motors: 2 to 10 V |
| IN1, IN2 | the signals for motor A |
| IN3, IN4 | the signals for motor B |
| Motor A, Motor B | the two motors |
- IN1 and IN2 from two pins: one HIGH and one LOW turns motor A, both LOW stops it.
- Join its GND to the GND of the board.
Good to know: Never run a motor straight from a board pin: the driver gives it the current.
