This is the casing for the Wemos D1 Mini (custom shield) RFTXRX (RF Transmitter/Receiver) .
This D1M BLOCK has a breakout for the cheaper 433/315 mHz units (MX-05V and MX-FS-03V). As long as the pin assignment and the power requirements are correct, other units may work as well.
These components, a SOCKET JIG for soldering, and 2 off 8 pin 10mm Long Needle Female Pin Header Strip are required for this build.
Align large, non-beveled surface to bed.
