Adafruit RFM95W LoRa Radio Transceiver Breakout - 868 or 915 MHz
- 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 or more radios, with matching frequencies. This +20dBm LoRa packet radios has a special radio modulation that is not compatible with the RFM69s but can go much much farther. They can easily go 2 Km (depends obstructions, frequency, antenna and power output) line of sight using simple wire antennas, or up to 20Km with directional antennas and settings tweakings
Uses the license-free ISM band: "European ISM" @ 868MHz or "American ISM" @ 915MHz
Use a simple wire antenna or spot for uFL or SMA radio connector
SX1276 LoRa® based module with SPI interface
+5 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software)
~100mA peak during +20dBm transmit, ~30mA during active radio listening.
Size: 1.14" x 1.0" x 0.2"
Some soldering required.
