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.
