The HC-12 is a 100mW multi-channel wireless transceiver you can use in your projects to transmit and receive serial information.
The HC-12 is a half-duplex wireless serial communication module with 100 channels in the 433.4-473.0 MHz range that is capable of transmitting up to 1 km. This project will begin by using the HC-12 to create a wireless link between two computers and end with a second article that creates a simple wireless GPS tracker.
