Product Description
The RFM95W Wireless Receiving Module (915 MHz) is a long-range RF communication module based on LoRa® modulation — typically using the SX1276/SX1278 chipset — designed for low-power wide area network (LPWAN) applications. Operating in the 915 MHz ISM band, this module can receive and transmit wireless data over long distances with high interference resistance and low power consumption.
Using an SPI interface for configuration and data exchange, the RFM95W integrates easily with microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi (via SPI). It excels in applications like remote sensor data collection, IoT telemetry, environmental monitoring, wireless control systems, and smart agriculture devices that require robust communication with minimal infrastructure.
