Elecrow nRFLRCC68 Wireless Transceiver Module integrates the Nordic nRF52840 microcontroller and the Semtech LLCC68 LoRa transceiver chip. It is a high-performance, low-power medium- and long-range Wireless 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 nRFLRCC68 Wireless Transceiver 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 nRFLRCC68 Wireless Transceiver 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 this Elecrow Wireless Transceiver Module more suitable for smart home applications, medium-range indoor and indoor-to-outdoor wireless applications.
Self-developed by Elecrow with exclusive design. Customization of this nRFLRCC68 Wireless Transceiver Module can be discussed for bulk orders.
