Adafruit RFM96W LoRa Radio Transceiver 433 MHz Breakout
The RFM96W LoRa Radio Transceiver 433 MHz modules are great for use with Arduinos or other microcontrollers, say if you want a sensor node network or transmit data over a campus or town.
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! 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 tweaking.
- 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.
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.
