This telemetry kit 433MHz for Pixhawk allows to establish a wireless connection between a drone and a ground device (tablet, smartphone, computer, etc.). This kit is based on open source software as an alternative to Xbee radios as offering better performance for a more competitive price.

The kit includes one serial board module to mount on your drone and one USB or Bluetooth to connect to your computer or tablet on the ground.

The system provides a full-duplex link using HopeRF's HM-TRP modules running custom, open source firmware.  The interface to the module is done via a standard 5V TTL serial / FTDI USB serial connection or direct USB.

The SiK firmware includes a bootloader that allows radio firmware upgrades over the serial interface, and radio firmware with configurable parameters.

Firmware upgrades and configuration are fully supported in the ArduPilot APM Mission Planner. Configuration is also possible through the 3DR Radio configurator and AT commands.
