Elecrow nRFLR1110 Wireless Transceiver Module-Integrates Nordic nRF52840 and Semtech LR1110¶

Description¶

Elecrow nRFLR1110 is a high-performance, low-power, long-range transceiver module that integrates 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 not only supports Bluetooth 5.3 and low-power Bluetooth, but also 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, Thread 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 and efficient solution.

Self-developed by Elecrow with exclusive design. Customization can be discussed for bulk orders.
