The Drotek Radio Telemetry Kit is available in 433Mhz or 915Mhz and in the following configurations: serial board (for the air) and USB (for the ground). Interface to the module is via standard 5V-tolerant TTL serial / FTDI USB serial. Firmware upgrades and configuration are fully supported in the APM Mission Planner.
Configuration is also possible through the 3DR Radio configurator and AT commands.
Warning : Frequency/power level regulations vary by country, so consult your local airspace authority to find out which frequency and power level are legal in your area. In Europe you should use the 433 MHz
