WS8403FLS is a wireless RF transceiver module designed based on Semtech's RF chip LLCC68, supporting the 868/915 frequency band, with a maximum transmission power of 22dBm, and extremely cost-effective.
This module adopts a brand new LoRaTM modulation technology, which has lower power density and stronger anti-interference performance compared to conventional FSK and GFSK modulation technologies, and can further improve communication reliability. Meanwhile, users can adjust the spreading modulation bandwidth, spreading factor, and error correction rate on their own.
The measured communication distance can reach 6Km
Supporting modulation methods: LoRaTM、(G)FSK
Supports 868/915MHz frequency band
Maximum transmission power of 160mW, power software adjustable
Supports data transmission rates of 1.76kbps to 62.5kbps in LoRaTM mode
Supports up to 300kbps data transmission rate in FSK mode
FIFO has a large capacity and supports 256Byte data caching
Supported spreading factors: 5-11
Supported encoding rates: 4/5, 4/6, 4/7, 4/8
Supports low-speed mode and can enable low-speed optimization
4-wire SPI communication interface, can be directly connected to various microcontrollers for use
Wide voltage operating range: 1.8V-3.7V
Industrial standard design, supporting long-term use at -40 ℃~85 ℃
Dual RF interface optional, U.LF connector or stamp hole
