WS8475 series mdoule is a multi-band LoRa data transmission module designed and manufactured by Silent SmartTechnology Co., Ltd.It adopts a high-performance MCU + Transceiver solution, supports low power consumption, and supports maximum transmit powers of 22dBm, 30dBm, and 33dBm. It supports 433/470MHz and 868/915MHz frequency bands, with a user packet length of 246 bytes, a 1K buffer, and supports various optional package sizes. It supports fixed-point transmission, transparent transmission, broadcast transmission, and WOR transceiver functions.
The WS8475 series supports random encryption, ensuring that the same data packet results in different over-the-air signatures each time it is transmitted. Featuring LoRa™ spread spectrum technology, the module leverages Direct Sequence Spread Spectrum (DSSS) to provide longer communication range, superior anti-interference capabilities, and enhanced security
