Also in this family: nRFLR1262, nRFLR1121, and nRFLRCC68. The Elecrow nRFLR1110 Wireless Transceiver Module is a high-performance, ultra-low-power, and long-range wireless solution that integrates the Nordic nRF52840 microcontroller with Semtech’s third-generation LR1110 LoRa transceiver. It delivers up to +21 dBm transmit power, supports a wide data rate range of 1.76–62.5 Kbps, and enables communication distances of up to 10 km, making it ideal for long-range IoT applications. The module supports Bluetooth 5.3, LoRaWAN 1.0.3 (Class A/B/C), and LoRa point-to-point (P2P) communication across the 850–930 MHz ISM band. It also supports Bluetooth Mesh, NFC, Thread, and Zigbee, allowing flexible wireless connectivity. A key highlight of the nRFLR1110 is its integrated GNSS (GPS/BeiDou) capability, enabling precise outdoor positioning and tracking. Combined with Wi-Fi passive scanning and Bluetooth mesh networking, it supports reliable indoor positioning systems (IPS), providing seamless indoor and outdoor coverage. With built-in AT command firmware, SDK support, and rich peripheral interfaces, the nRFLR1110 is a powerful and flexible platform for applications such as asset tracking, anti-theft systems, recovery, and traceability.
