Also in this family: the LR1262 (higher sensitivity) and the nRFLRCC68 (adds nRF52840 MCU + BLE). The LRCC68 Long-Range LoRa Wireless Transceiver Module is a compact and efficient wireless solution based on the Semtech LLCC68 LoRa chip, designed for operation in the 868 MHz and 915 MHz ISM bands. With its ultra-small 10 × 10 mm stamp-hole package, the module is easy to integrate into custom PCBs and embedded systems. It utilizes advanced LoRa modulation technology, providing superior anti-interference performance and extended communication range compared to traditional FSK and GFSK solutions. The module delivers up to +22 dBm transmit power, supports data rates from 1.76 to 62.5 Kbps, and operates across the 850–930 MHz global LoRa & LoRaWAN ISM band, making it suitable for worldwide IoT deployments. Equipped with an industrial-grade TCXO, the LRCC68 ensures stable operation across harsh environments. With an ultra-low sleep current of just 1.62 µA, it is ideal for battery-powered and low-power IoT applications. Note: This module requires an external MCU driver or a dedicated SPI debugging tool for proper operation.
