The WS8419DLS is a wireless RF transceiver module designed based on Semtech's SX1278 RF chip. This module employs the new LoRa ™ modulation technology, which, compared to conventional FSK and GFSK modulation technologies, offers lower power density and stronger anti-interference performance, further improving communication reliability. Furthermore, users can adjust the spread spectrum modulation bandwidth, spreading factor, and error correction rate themselves.
Supports license-free ISM 433 MHz band 470 MHz meter reading band
It adopts LoRa spread spectrum technology, which has strong anti-interference performance and long communication distance
Supports a maximum transmit power of 20 dBm (approximately 100 mW )
Supports high over-the-air speeds, up to 300kbps
Supports LoRa ™ and (G)FSK modulation
RF interface stamp hole
4-wire SPI communication interface
Industrial-grade standard design, Supports long-term use at temperatures ranging from -40°C to +85 °C
