WS8403DLS is a wireless RF transceiver module designed based on Semtech's RF chip LLCC68. It supports 433/470MHz frequency bands, has a maximum transmit power of 22dBm, and is extremely cost-effective.
This module uses the new LoRaTM modulation technology. Compared with conventional FSK and GFSK modulation technologies, it has low power density and stronger anti-interference performance, which can further improve communication reliability. At the same time, users can adjust the spread spectrum modulation bandwidth, spread spectrum factor and error correction rate by themselves.
The measured communication distance can reach 6Km
