The Elecrow nRFLR1121 module integrates the Nordic nRF52840 microcontroller and the Semtech LR1121 LoRa transceiver chip. It is a high-performance, low-power, long-range transceiver module. It supports Bluetooth 5.3 and low-power Bluetooth, complies with the A, B, and C classes of the LoRaWAN 1.0.4 specification. And it supports LoRa point-to-point (P2P) communication mode, covering the 850~930MHz (applicable to 868MHz, 915MHz) global ISM frequency band, with a maximum transmit power of +20dBm, a transmission rate range of 1.91~62.5Kbps, and a transmission distance of up to 10 km. In addition, the module supports ground ISM band communications, covering the global 2.4GHz spectrum and Sub-GHz band, and also supports S-band LR-FHSS (Long Range - Frequency Hopping Spread Spectrum) technology for satellite connection (the two cannot work at the same time). This makes it suitable for remote areas without ground network coverage, such as environmental monitoring of meteorological stations and hydrological stations and transmits data to the central server via satellite communication. The nRFLR1121 module has built-in AT command firmware, supports SDK customized development, and rich peripheral interfaces provide high flexibility to meet diverse development needs. Designed in accordance with industrial standards, the nRFLR1121 module is an ideal choice for high-reliability applications such as remote monitoring, ship communications, and rescue missions.
