The Elecrow nRFLR1121 Wireless Transceiver Module combines the powerful Nordic nRF52840 microcontroller with the advanced Semtech LR1121 LoRa transceiver, delivering a high-performance, ultra-low-power, and long-range wireless communication solution.
Supporting Bluetooth 5.3, LoRaWAN 1.0.4 (Class A/B/C), and LoRa point-to-point (P2P) communication, this module operates across the 850–930 MHz ISM band (including 868 MHz and 915 MHz). It offers a maximum transmit power of +21 dBm, data rates from 1.91 to 62.5 Kbps, and communication distances of up to 10 km.
The module also supports global 2.4 GHz spectrum and Sub-GHz communication, along with S-band LR-FHSS (Long Range – Frequency Hopping Spread Spectrum) for satellite connectivity (note: satellite and terrestrial modes cannot operate simultaneously). This makes it ideal for remote and infrastructure-free environments, such as meteorological and hydrological monitoring systems.
With built-in AT command firmware, SDK support for custom development, and rich peripheral interfaces, the nRFLR1121 module is designed for industrial-grade reliability and flexibility.
