Frequency: The module operates in the 433MHz ISM (Industrial, Scientific, and Medical) band. This frequency range is commonly used for various wireless applications and allows for relatively good propagation characteristics.
Range: The module is advertised to have a range of up to 1 kilometer in open spaces. However, the actual range can vary depending on factors like obstacles, interference, and the quality of the antennas used.
Data Rate: The HC-12 supports a range of configurable data rates, typically from 1.2 kbps up to 115.2 kbps. The data rate can be adjusted to balance between data throughput and transmission range.
Serial Communication: The module communicates with the host microcontroller (such as Arduino, Raspberry Pi, etc.) using UART (Universal Asynchronous Receiver-Transmitter) serial communication. This means you can use it to wirelessly extend the serial communication of your device.
Configuration: The HC-12 modules usually feature a set of AT commands that allow you to configure various parameters, such as frequency, data rate, power level, and more.
Power Supply: The module typically operates at 3.2V to 5.5V DC, making it compatible with a variety of power sources.
Antenna: The quality and type of antenna used can significantly affect the range and performance of the module. Some HC-12 modules come with onboard antennas, while others might have connectors for external antennas.
