This Radio Telemetry kit offers a great low price, longer range (approx one mile with supplied antennas) and superior performance. The system utilizes 433Mhz band and provides a full-duplex link using HopeRF's HM-TRP modules running custom, open source, firmware

The SiK firmware includes a bootloader that permits radio firmware upgrades over the serial interface, and configuration of system parameters. Firmware upgrades and configuration are fully supported in the APM Mission Planner. Configuration is also possible through the 3DR Radio configurator and AT commands.

Kick your mission planning into real time with Radios, featuring interchangeable air and ground modules, Android tablet compatibility, and protective cases. Radios allow your ground station computer to communicate with your vehicle wirelessly, providing unparalleled ease of use for viewing in-flight data, changing missions on the fly.

Interface to the module is via standard 5V-tolerant TTL serial / FT230 USB serial.
