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.

HM-TRP features:

  • Small size and light weight
  • Available in 433Mhz and 915MHz variants
  • Receiver sensitivity to -121 dBm
  • Transmit power up to 20dBm (100mW)
  • Transparent serial link
  • Air data rates up to 250kbps
  • MAVLink protocol framing and status reporting
  • Frequency hopping spread spectrum (FHSS)
  • Adaptive time division multiplexing (TDM)
  • Configurable duty cycle
  • Built in error correcting code (can correct up to 25% data bit errors)
  • Demonstrated range of several kilometers with a small omni antenna
  • Can be used with a bi-directional amplifier for even more range
  • Open source firmware
  • AT commands for radio configuration
  • RT commands for remote radio configuration
  • Based on the HopeRF HM-TRP radio module, with an SiLabs Si1000 RF microcontroller
  • Transmit current: 100 mA at 20 dBm
  • Receive current: 25 mA


Board features:

  • Supply voltage: 3.3-5 VDC
  • Serial interface: 3.3 V UART
  • JST-GH connector
  • Micro USB port
  • SMA connector
  • Weight: 6g
  • 17 mm x 52 mm
  • Designed and manufactured in France


Package content:

  • Telemetry module x2
  • JST-GH 6Pin cable x2



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.

In Europe you should use the 433 MHz
