Trying to identify this component board, but cannot find any information about it

Hope to find answers here on the forum. Or if anyone can show me in the right direction 😁

Re: Unknown control module on electric ATV

The little board is an RF remote control receiver, ASK or OOK. It receives data from the wireless remote and sends serial data to the SC2272 remote control decoder IC.

The red trimmer cap is for tuning the receiver to match the remote's transmit frequency. You can troubleshoot by looking for signal at the little board's DATA pin. There should be the usual noise and a burst of data when the remote button is pressed.
