The JZX813 data transmission module is a highly integrated spread spectrum half duplex wireless data transmission module, which uses the "LoRa" high-performance low-power RF chip and high-speed microcontroller.
The JZX813 module provides 16 channels, with the first 8 channels in the 433MHz frequency band and the last 8 channels in the 490MHz frequency band. And it is equipped with professional setting software for users to make parameter changes. The module adopts a transparent transmission method, and users do not need to write setting and transmission programs to transmit data of any size. The module has a small size, wide voltage range, and is convenient to use.
