Adafruit RFM69HCW Transceiver Radio Bonnets

Adafruit RFM69HCW Transceiver Radio Bonnets are Raspberry Pi computers with WiFi, BLUETOOTH®, and other radio options. Upgrade a Raspberry Pi with a sub-GHz radio transceiver to communicate over long distances. The bonnets plug into a Pi and give long-range wireless capabilities to remote nodes that can be battery-powered or easily create Internet gateways.

Included is a 128x32 OLED display for status messages and three buttons for creating a custom user interface or sending test messages. Everything above is supported by Python libraries to send or receive packetized radio data with other matching modules in a network. Gateways can be crafted using the Pi's built-in networking capabilities.


  • Packet radio with ready-to-go CircuitPython libraries
  • SX1231-based module with SPI interface
  • +13dBm to +20dBm up to 100mW power output capability (power output selectable in software)
  • 50mA (+13dBm) to 150mA (+20dBm) current draw for transmissions, ~30mA during active radio listening
  • Range of approx. 500 meters, depending on obstructions, frequency, antenna, and power output
  • Create multi-point networks with individual node addresses
  • Encrypted packet engine with AES-128
  • Variants
    • 4072 - uses the license-free ISM band: "European ISM" at 868MHz or "American ISM" at 915MHz
    • 4073 - 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
