PT2262 PT2272 hard-coded 433M remote control relay,

Overview

For the receiving part, I bought a SYN480R 433M decoding module online, so there is no model number for the decoding part. The LC value of the transmitting part components needs to be tested in practice, and it is not the best value. I used the components I have here to test. The maximum communication distance is 10 meters. If the transmitting part is well matched, it should be farther. The receiving part uses PT2272 L4S with self-locking buttons. If you need to jog, just change it to M4
