JZX875 data transmission module is a highly integrated low-power half-duplex wireless data transmission module, which uses "TI" high-performance RF chip and high-speed single-chip computer. The module provides 16 channels, and is equipped with professional setup software, so that users can change parameters. The module adopts transparent transmission mode, and can transmit data of any size without user writing setup and transmission program. Industrial-grade design, transmitter power can be set, module size is small, the use of voltage is wide, easy to use.
