Frequently asked questions
What motor current can this module handle?
The output current is rated below 2 A. For motors that draw more than this, including at stall, choose a driver with a higher current rating.
How is the speed set?
Speed is set by turning the onboard potentiometer. The listing does not mention an external PWM input, so check the board's pin labels before wiring a microcontroller signal to it.
