This 915MHz Radio Telemetry Kit is useful for communication between a quadcopter, helicopter or other airborne UAV and your laptop.


  • Compatible with:
    • 3DRobotics 3DR Radio Telemetry Kit 915Mhz
    • APM 2.5
    • APM2.6
    • Pixhawk
    • Arduino
    • Raspberry Pi
  • Pre-programmed to the correct baud rate just connect to your quadrino and start changing PIDs on the fly
  • Designed as an open source Xbee replacement radio set, offering a lower price, longer range and superior performance to Xbee radios.
  • Frequency: 915Mhz
  • Serial board (air unit) and USB (ground unit)
  • The radio is a 2-way half-duplex wireless communication system with a standard TTL UART interface, based on HopeRF's HM-TRP data link modules, and custom firmware that improves upon the modules' original features and performance.
  • The SiK firmware includes a bootloader that permits radio firmware upgrades over the serial interface, and radio firmware with configurable parameters. Firmware upgrades and configuration are fully supported in the APM Mission Planner. Configuration is also possible through AT commands.
