RFM95W LoRa Radio Module 915MHz

The RFM95W is a high-performance LoRa radio transceiver module built around the Semtech LoRa chipset, designed for long-range, low-power wireless communication in IoT and remote sensing projects. Operating in the license-free 915MHz ISM band, this module uses Chirp Spread Spectrum modulation to achieve exceptional receiver sensitivity and strong immunity to interference, allowing it to maintain reliable links over distances that far exceed typical Wi-Fi, Bluetooth, or Zigbee ranges. With a simple wire antenna, it can easily reach line-of-sight distances of around 2km, and with directional antennas and tuned settings, ranges of up to 20km are achievable.

This module is a favourite among makers building LoRaWAN nodes, remote telemetry systems, agricultural sensors, environmental monitoring stations, and long-range alert or asset-tracking devices. It communicates over SPI, making it straightforward to interface with Arduino, ESP32, Raspberry Pi, and other microcontrollers, and supports FSK, GFSK, MSK, GMSK, and OOK modulation in addition to LoRa, giving developers flexibility across different protocol requirements. Its onboard +20dBm power amplifier combined with industry-leading receiver sensitivity delivers an outstanding link budget, making it well suited for challenging RF environments.

Whether you’re building a LoRaWAN sensor network, a long-range remote control system, or a solar-powered field monitoring node, the RFM95W offers a dependable, efficient, and widely supported foundation for low-power wide-area wireless communication.
