Product Description:
The RFM69HW-433S is a high-performance 433 MHz ISM band transceiver module designed for reliable, long-range, and low-power wireless communication. Featuring a built-in 20 dBm RF power amplifier, this module is ideal for IoT networks, smart home devices, industrial telemetry, and remote control systems.
Operating at 1.8 V to 3.6 V DC, the RFM69HW supports multiple modulation formats — FSK, GFSK, MSK, GMSK, OOK, and ASK — with data rates up to 300 kbps. Its excellent receiver sensitivity of −120 dBm ensures stable communication even in noisy environments.
Integrated CRC-16 error checking and AES-128 hardware encryption provide secure and error-free data transmission. Fully compatible with Arduino, STM32, ESP32, and other microcontrollers via SPI interface, this module is an excellent choice for both hobby and professional wireless communication applications.
