Elecrow nRFLR1121 Wireless Transceiver Module with nRF52840 & SX1121-1

Elecrow nRFLR1121 Wireless Transceiver Module with nRF52840 & SX1121

€18,95

Elecrow nRFLR1121 Wireless Transceiver Module integrates the Nordic nRF52840 microcontroller and the Semtech LR1121 LoRa transceiver chip. It is a high-performance, low-power, long-range Wireless 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 Elecrow nRFLR1121 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 the nRFLR1121 Wireless Transceiver Module 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.
