RFM69HCW 915 MHz Wireless Receiving Module

RFM69HCW 915 MHz Wireless Receiving Module 

The RFM69HCW 915MHz Wireless RF Module is a high-performance, low-power sub-GHz wireless transceiver module designed for reliable long-range communication in the 915MHz ISM band. It is based on the Semtech / HopeRF RFM69 series chipset and supports both transmit and receive functions with excellent sensitivity and strong interference resistance.

This module uses FSK / GFSK / OOK / MSK modulation and communicates with microcontrollers via SPI interface, making it easy to integrate with Arduino, ESP32, STM32, Raspberry Pi, and other controllers. With its high output power and low power consumption, it is ideal for IoT, remote sensing, home automation, and wireless data communication projects.
