Radio Telemetry Kit (433Mhz or 915Mhz)
The Drotek telemetry system base on 3DR Radio system and 100% compatible. It's designed as an open source Xbee replacement radio set, offering a lower price, longer range (approx one mile) and superior performance to Xbee radios.
It’s available in 433Mhz or 915Mhz and in the following configurations: serial board (for the air) and USB (for the ground). The system provides a full-duplex link using HopeRF's HM-TRP modules running custom, open source firmware. 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.
Attention: 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.
