Adafruit RFM69HCW Transceiver Radio Breakout - 868 or 915 MHz

Sending data over long distances is like magic, and now you can be a magician with this range of powerful and easy to use radio modules. Sure, sometimes you want to talk to a computer using WiFi, or communicate with a phone through Bluetooth Low Energy. However, when the goal is transmitting data far afield, these radio modules provide the ideal solution.

Most WiFi, Bluetooth, Zigbee, and other wireless chipsets operate on 2.4 GHz, perfect for high-speed transfers. While these frequencies excel at data-intensive tasks like streaming video, lower license-free frequencies such as 433 MHz or 900 MHz allow for greater range, albeit at lower data rates.

Benefits and Features: - Simple operation without the need for pairing or connection maintenance. - Automatic packetization and error correction with optional auto-retransmit. - Suitable for use with Arduinos or other microcontrollers to create sensor networks or transmit data over larger distances. - Available in four variants with two modulation types and two frequencies. - Operates on the license-free ISM band at either 868 MHz or 915 MHz, depending on software tuning.- A range of approximately 500 meters with basic wire antennas, extensible up to 5 km with optimal settings and directional antennas. - Secure transmissions using an encrypted packet engine with AES-128.

This 900 MHz radio can be tuned for either 868 MHz or 915 MHz. All radios are sold individually and must match frequencies and modulation types for communication. Each radio includes header, a 3.3V voltage regulator, and a level shifter, adaptable for 3V or 5V devices. Some assembly, including soldering and antenna setup, is required. For higher performance, consider adding a uFL or SMA connector for external antennas. Explore our tutorials for wiring diagrams and example code.
