LoRa module – RFM95

The RFM95W-868S2R is a compact LoRa module based on the Semtech SX1276/SX1278 transceiver chip, operating in the 868MHz ISM band. It utilizes LoRa modulation for ultra-long-range spread spectrum communication, offering exceptional sensitivity of up to -148dBm and high interference immunity. Key features include programmable bit rates up to 300 kbps, a built-in temperature sensor, low battery indicator, and a packet engine with CRC support. With low current consumption (as low as 200nA in sleep mode), it's perfect for battery-powered IoT devices. Common applications include smart home automation, remote environmental monitoring, industrial telemetry, and agricultural sensor networks. This module is an excellent choice for developers needing reliable, long-range wireless connectivity in India's 868MHz frequency band, offering a balance of performance, power efficiency, and ease of integration via SPI interface.
