HopeRF RFM95PW-868S2 LoRa Module 868MHz

Description

The HopeRF RFM95PW-868S2 is a core building block for LPWAN networks, leveraging the proven RF98/RF96 chipset to implement the LoRa physical layer. Its design prioritizes both range and power efficiency, enabling battery-operated sensor nodes to transmit data over several kilometers in open terrain. The module’s advanced modem features, including a built-in bit synchronizer and fast AFC, ensure stable communication even in noisy RF environments.

Engineered for seamless integration, the module operates from a single 3.3V supply and communicates through a standard SPI interface, making it compatible with a wide range of microcontrollers like ESP32, STM32, and Arduino platforms. The integrated packet engine handles payloads up to 256 bytes, offloading complex timing and synchronization tasks from the host MCU. This combination of high performance, low current consumption in sleep modes, and a compact form factor makes it a premier choice for industrial telemetry, smart agriculture, automated meter reading, and asset tracking systems.
