The nRFLR1110 is a high-performance, low-power, long-range transceiver module integrating the Nordic nRF52840 microcontroller and Semtech's latest third-generation LR1110 LoRa transceiver chip. Its maximum transmit power is up to +20dBm, the transmission rate range is wide, from 1.76~62.5Kbps, and the transmission distance can reach 10KM.
This module supports Bluetooth 5.3 and low-power Bluetooth and complies with the A, B, and C classes of the LoRaWAN1.0.4 specification. It also supports LoRa point-to-point (P2P) communication mode, 850~930MHz global LoRa&LoRaWAN ISM frequency, providing strong support for quickly building custom LoRa networks. In addition, it also supports network protocols such as Bluetooth mesh, NFC, Threa,d, and Zigbee.
nRFLR1110 uses the built-in high-performance GNSS (Global Navigation Satellite System) tracking function of LR1110 for outdoor precise positioning and tracking. At the same time, its Wi-Fi passive scanning and Bluetooth mesh network functions make it perform well in indoor positioning systems (IPS), achieving full coverage indoors and outdoors, reducing system complexity and cost. nRFLR1110 is the perfect development platform for applications such as asset management, positioning, recovery, traceability, anti-loss, and theft, providing developers with a powerful, flexible,e and efficient solution.
