This board provides an “open collector” output in response to a remote control press.
It’s compatible with many of the AVD Halloween prop controllers and plugs in place of the IR trigger.
Up to 4 of these boards can be used with just one 4 button transmitter.
A jumper selects which button (A, B, C, D) the board responds to.
For systems with more than 4 receiver boards, use 2 remote controls.
The receiver is paired with the remote control. More than one remote can trigger the same board if desired.
Details on how to pair the remote key fob and receiver module here.
