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. The trade off is you need two or more radios, with matching frequencies. WiFi and BT, on the other hand, are commonly included in computers and phones.

These radio modules come in four variants (two modulation types and two frequencies) The RFM69's are easiest to work with, and are well known and understood. The LoRa radios are exciting and more powerful but also more expensive.

This is the LoRa radio module 433 MHz version! We also carry a 900 MHz version here. These are +20dBm LoRa packet radios that have a special radio modulation that is not compatible with the RFM69s but can go much much farther. They can easily go 2 Km line of sight using simple wire antennas, or up to 20Km with directional antennas and settings tweakings

Packet radio with ready-to-go Arduino libraries
Uses the amateur or license-free ISM band (ITU "Europe" license-free ISM or ITU "American" amateur with limitations)
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.
Range of approx. 2Km, depending on obstructions, frequency, antenna and power output
All radios are sold individually and can only talk to radios of the same part number. E.g. RFM69 900 MHz can only talk to RFM69 900 MHz, LoRa 433 MHz can only talk to LoRa 433 MHz, etc.

Each radio comes with some header, a 3.3V voltage regulator and levelshifter that can handle 3-5V DC power and logic so you can use it with 3V or 5V devices. Some soldering is required to attach the header. You will need to cut and solder on a small piece of wire (any solid or stranded core is fine) in order to create your antenna. Optionally you can pick up a uFL or SMA edge-mount connector and attach an external duck.
