Also in this family: nRFLR1262, nRFLR1110, and nRFLR1121. The Elecrow nRFLRCC68 Wireless Transceiver Module integrates the powerful Nordic nRF52840 microcontroller with the Semtech LLCC68 LoRa transceiver, offering a cost-effective, high-performance, and low-power solution for medium- and long-range wireless communication. It supports Bluetooth 5.3, LoRaWAN 1.0.3 (Class A/B/C), and LoRa point-to-point (P2P) communication, operating across the 850–930 MHz ISM band (including 868 MHz and 915 MHz). The module delivers up to +20 dBm transmit power, data rates from 1.76 to 62.5 Kbps, and communication distances up to 10 km. Designed with cost optimization in mind, this module retains key advantages such as low power consumption and high transmit performance while removing less commonly used ultra-low-rate scenarios. This makes it especially suitable for smart home applications and medium-range indoor or indoor-to-outdoor communication systems. With built-in AT command firmware, SDK support for customization, and rich peripheral interfaces, the nRFLRCC68 provides flexibility and ease of integration for a wide range of IoT applications.
