Frequently asked questions
How should I wire the module?
Connect 12 V DC and match the positive and negative leads to the markings on the module, since the listing specifically warns about +ve and -ve. Use a supply that can provide at least 3 A, the top of the listed 1-3 A current range.
Can I control it from a microcontroller?
Yes, the module has a TTL driver input, so it can be switched with a TTL-level signal from a microcontroller. Confirm the signal levels and the control pin from the module's own labels before connecting.
