RFM69HCW 434 MHz Wireless Receiving Module

RFM69HCW 434 MHz Wireless Receiving Module 

The RFM69HCW 434MHz Wireless RF Module is a high-performance, low-power sub-GHz wireless transceiver module designed for reliable long-range communication in the 433/434MHz ISM band. It is based on the HopeRF / Semtech RFM69 series chipset and supports both transmitting and receiving 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 high output power and low power consumption, it is ideal for IoT, remote monitoring, home automation, and wireless data communication projects.
