Semtech LLCC68 LoRa Module RC68D

The RC68D is a high-performance, ultra-low-power, low-cost LoRa^® module designed by RF Crazy Technology based on the Semtech LLCC68 RF transceiver. It supports traditional (G) FSK mode and LoRa modulation function, up to +15 dBm transmission power, and can guarantee long-distance spread spectrum communication. Only 4.2 mA of active reception consumes power, and the system is designed to achieve long battery life. The RC68D adopts the form of a stamp welding port, providing an IPEX antenna holder and an external antenna pin. This allows you to easily integrate the module into the device motherboard, greatly saving your budget and time in the entire product design process.The RC68D module is highly suitable for remote ultra-low-power wide-area IoT scenarios such as smart agriculture, smart cities, wireless meter readings, sensor networks, and wireless communications.
