Frequently asked questions
What does non-locking mean?
Each channel output stays active only while its transmitter button is held down and turns off when released. If you need a toggle action, add a latching stage in your hardware or code.
How should I power the transmitter and receiver?
The receiver is rated for 5 V DC, which matches a 5 V supply such as an Arduino 5 V pin. The transmitter needs 12 V DC, so power it from a separate 12 V source. The listed transmission distance is 3 to 5 m.
