Why Choose This?
- Genuine HopeRF Quality: Unlike unbranded RF modules prone to frequency drift and poor sensitivity, the RFM69HW uses a proven Semtech SX1231H transceiver IC for consistent, reliable performance across temperature extremes.
- High Power + Hardware Encryption: The +20 dBm output power enables communication ranges exceeding 1 km in open air, while built-in 128-bit AES encryption secures your data without burdening your microcontroller.
- Bengaluru-Based Expert Support: Get fast shipping across India, hands-on technical guidance, and access to tested Arduino and STM32 code libraries directly from The Engineer Store team.
Project Ideas
- Farm Sensor Network: Deploy soil moisture, temperature, and humidity sensors across agricultural land with wireless data relay to a central gateway over long distances.
- Home Automation Hub: Build a secure, encrypted wireless network connecting smart switches, door sensors, and alarm systems throughout your home without relying on Wi-Fi.
- Weather Station Mesh: Create a distributed weather monitoring system with multiple nodes transmitting barometric pressure, wind speed, and rainfall data to a Raspberry Pi base station.
What's in the Box
- 1x RFM69HW-868S2R RF Transceiver Module
- Note: Antenna and header pins are not included - a 868MHz quarter-wave wire antenna (82.2 mm) is recommended
Frequently Asked Questions
What is the communication range of the RFM69HW-868S2R?
With the +20 dBm high-power output and a proper 868MHz antenna, you can achieve line-of-sight ranges of 1 km or more. In urban environments with obstacles, expect 200-500 meters depending on antenna quality and placement.
Can I use this module with Arduino?
Yes. The RFM69HW communicates over SPI and works seamlessly with Arduino Uno, Nano, Mega, and ESP32 boards. The popular RadioHead and LowPowerLab RFM69 libraries provide ready-to-use code for quick integration.
Is the 868MHz band legal to use in India?
The 865-867 MHz band is permitted for low-power short-range devices in India under the Department of Telecommunications guidelines. Always verify current regulations and ensure your transmission power and duty cycle comply with local rules.
What antenna should I use with this module?
A simple 82.2 mm straight wire soldered to the antenna pad works well as a quarter-wave antenna. For better performance, use a 868MHz SMA antenna with a U.FL to SMA pigtail adapter.
Can two RFM69HW modules communicate with each other directly?
Yes. The RFM69HW is a full transceiver - it can both send and receive. Two modules running the same library and configured to the same frequency and network ID will communicate directly in a peer-to-peer or star topology.
How does the RFM69HW differ from the RFM69W?
The RFM69HW is the high-power variant with +20 dBm maximum output power compared to +13 dBm on the standard RFM69W. This gives the HW version significantly greater range, making it ideal for outdoor and long-distance applications.
