The WS8425FLS is a wireless transceiver module developed based on Semtech's latest generation LoRa® chip, the LR2021. It not only continues the advantages of LoRa's long-range communication but also achieves a leap from "low-speed sensing" to "high-speed transmission".

The WS8425FLS features a typical receiver sensitivity of -143 dBm (SF12/62 kHz). The WS8425FLS adds support for FLRC in the Sub-GHz band, enabling transmission rates up to 2.6 Mbps (up to 125 kbps in standard LoRa mode). This significant bandwidth increase allows the WS8425FLS to support image transmission, voice/audio clip delivery, and larger-scale packet updates.

The WS8425FLS supports commonly used Sub-GHz (850-930MHz) and 2.4 GHz ISM bands.

While maintaining low power consumption with a sleep current of ≤3.5 µA, the WS8425FLS integrates LR-FHSS frequency hopping spread spectrum technology to cope with strong interference environments, supports RTTofF ranging, and is fully compatible with mainstream IoT protocols such as LoRaWAN, BLE 5.0, and Wi-SUN.
