Adafruit RFM95W LoRa Radio Transceiver Breakout - 868 or 915 MHz

Key Features: New in 2020 - radio module comes with a protective tin to keep it a little safer from the elements Packet radio with ready-to-go Arduino libraries 900 MHz radio version, used for 868MHz or 915MHz transmission/reception Simpler than WiFi or BLE, you dont have to associate, pair, scan, or worry about connections 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. All you do is send data whenever you like, and any other modules tuned to that same frequency (and, with the same encryption key) will receive. The receiver can then send a reply back. The modules do packetization, error correction and can also auto-retransmit so its not like you have worry about everything but less power is wasted on maintaining a link or pairing.These modules are great for use with Arduinos or other microcontrollers, say if you want a sensor node nework or transmit data over a campus or town. You'll just need two
