433MHz wireless RF transceiver module (HC-11)

The HC-11 is a popular 433MHz wireless RF transceiver module used in DIY electronics. It allows microcontrollers (like Arduino) to communicate wirelessly over serial. It acts as a transparent "wireless cable," meaning whatever data goes into the TX/RX pins of one module is instantly transmitted to the other. M(4, 1)
