The HC-12 wireless RF UART communication module is a next-generation wireless data transmission module for embedded systems. It operates on a radio frequency range of 433.4-473.0MHz and can be configured to use any of its 100 communication channels, with each channel having a step size of 400kHz. The module has a maximum transmit power of 100mW (20dBm) and can receive signals as low as -116dBm with a baud rate of 5000bps, providing a communication distance of about 500 meters.
This Rf module is designed using a stamped hole encapsulation method, which makes it easy to weld. Its compact size of 27.4mm13.2mm4mm (including antenna seat but excluding the spring antenna) makes it convenient for embedding into the application system. The module comes with a PCB antenna seat ANT1, and users can also use an external antenna in the 433MHz band by connecting a coaxial cable.
The HC12 Module also features an antenna welding hole ANT2 for attaching a spring antenna, giving users the option to choose the antenna type based on their requirements. The module is equipped with an MCU, eliminating the need for additional programming. Users can simply send and receive UART data using one of the four UART modes of FU1, FU2, FU3, or FU4, which have an average operating current of 3.6mA, 80?A, 16mA, and 16mA, respectively. The module also supports AT commands for UART transmission mode selection.
The HC12 module is based on the SI4463 EZRadioPro family chip by SiLabs and offers an impressive wireless data transmission and reception range of up to 1 km in open air environments. The module is low power and very user-friendly.

HC 12 Module is a half-duplex multi-channel wireless transceiver module. It can be easily used to create a wireless communication between two microcontrollers. It is a 433 mHz transceiver that easily allows one Microcontroller to transfer or receive data to another microcontroller. The HC 12 module (HC12) is also known as si4463 wireless serial module. It is a low-cost transceiver module. One can easily buy HC 12 from Robocraze.
HC 12 module does not require any additional libraries that makes it extremely easy to use. The transferring and receiving of data can be done through transmitter (Tx) and Receiver (Rx) pins respectively. So, all you need to do is send data from transmitting Arduino and Receive data to Receiving Arduino.
To pair the HC12 Module with Arduino Uno follow the below mentioned steps:
That’s it. Next Upload the program through the Arduino IDE.
