Overview

The latest Raspberry Pi computers come with WiFi and Bluetooth, and now you can add even more radio options with the Adafruit Radio Bonnets! Upgrade your Raspberry Pi with a LoRa / LoRaWAN radio, so it can communicate over very long distances. These bonnets plug right into your Pi and give you long range wireless capabilities to remote nodes that may be battery powered. Or, you can create Internet gateways with ease.

You not only get a radio module, but also a 128x32 OLED display for status messages and three buttons you can use for creating a custom user interface or sending test messages. All of the above is supported with our Python libraries so you can send or receive LoRa data with other matching modules, send data to a LoRaWAN gateway, or even set up your own single channel LoRaWAN-to-Internet gateways.

Compared to the 2.4 GHz WiFi/Bluetooth radios on the Pi already, these modules run at 433 or 900 MHz (sub-GHz). You can't send data as fast but you can send data a lot farther. These packet radios are simpler than WiFi or BLE, you don't have to associate, pair, scan, or worry about connections. 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 it's not like you have worry about everything but less power is wasted on maintaining a link or pairing.

This is the 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically. 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

Specification

  • Packet radio with ready-to-go CircuitPython libraries
  • 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.
  • Range of approx. 2Km, depending on obstructions, frequency, antenna and power output

Technical Details

  • Dimensions: 65.2 x 30.6 x 9mm
  • Weight: 11g
