Product Introduction
Full duplex 433M wireless data transmission radio station, point-to-point (one-on-one, nonbroadcast) transmission. The module can send data while receiving it, without waiting for the reception to complete. The module has the function of Frequency Hopping and Spreading (FHSS), and both the transmitter and receiver will automatically synchronize hopping in up to 50 frequency points based on the hopping algorithm (users can customize the number and sequence of hopping), greatly improving anti-interference performance.
