RFM95W-868S2
Overview
The RFM95W-868S2 is a high-performance LoRa transceiver module designed for long-range wireless communication in the 868MHz band. It utilizes the Semtech SX1276 core to provide exceptional receiver sensitivity and integrated +20dBm power amplification, enabling robust links even in challenging RF environments. With its low 0.2uA sleep current and 1.8V to 3.7V operating range, it is optimized for battery-powered IoT edge devices.
Why Choose This Part
The module offers a superior link budget with -123dBm sensitivity and high interference immunity via LoRa spread-spectrum modulation. Its compact 16x16mm SMD form factor and 5V tolerant I/O pins simplify integration with a wide variety of microcontrollers. Engineers benefit from significantly reduced power consumption during idle states, extending the life of remote deployments.
Applications
Key Specifications
Getting Started
Integration is typically handled via an SPI interface and basic GPIOs for interrupts (DIO pins) and reset. For prototyping, the module is widely supported by the RadioHead and LMIC libraries for Arduino and Mbed environments. Ensure a proper 868MHz antenna is connected to the ANT pin before powering the module to avoid damaging the output stage.
