The nRFLRCC68 module integrates the Nordic nRF52840 microcontroller and the Semtech LLCC68 LoRa transceiver chip. It is a high-performance, low-power medium- and long-range 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 supports LoRa point-to-point (P2P) communication mode. It covers the 850~930MHz (applicable to 868MHz, 915MHz) global ISM band, with a maximum transmit power of +20dBm, a transmission rate range of 1.76~62.5Kbps, and a transmission distance of up to 10 km.
The nRFLR1121 module has built-in AT command firmware, supports SDK customized development, and a rich peripheral interface that provides high flexibility to meet diverse development needs. The nRFLR1121 module retains the advantages of low power consumption, high transmit power, and full LoRa frequency band, while optimizing the cost structure, removing the less used "ultra-low rate scenario", achieving significant price advantages, making it more suitable for smart home applications, medium-range indoor and indoor-to-outdoor wireless applications.
