The Elecrow nRFLR1262 module integrates the Nordic nRF52840 microcontroller and the Semtech SX1262 LoRa transceiver chip. It is a high-performance, low-power, and long-distance transceiver module. Its maximum transmit power is up to +20dBm, the transmission rate range is wide, from 0.018~62.5Kbps, and the transmission distance can reach up to 10KM.
This module supports Bluetooth 5.3 and low-power Bluetooth and complies with the A, B, and C classes of the LoRaWAN 1.0.3 specification. It also supports LoRa point-to-point (P2P) communication mode, covering the 850~930MHz global LoRa&LoRaWAN ISM frequency, providing strong support for quickly building a custom LoRa network.
The built-in AT command firmware supports customized SDK development, and the rich peripheral interfaces provide great flexibility to meet diverse development needs. Designed to industrial standards, the nRFLR1262 is an ideal choice for developing low-power, long-distance IoT applications for various scenarios requiring efficient communication and energy management.
Self-developed by Elecrow with exclusive design. Customization can be discussed for bulk orders.
