Product Description

Details

The 3DR Radio telemetry system is designed as an open source Xbee replacement radio set, offering a lower price, longer range and superior performance to Xbee radios.

The radio is a 2-way half-duplex wireless communication system with a standard TTL UART interface, based on HopeRF's HM-TRP data link modules, and custom firmware that improves upon the modules' original features and performance. The SiK firmware includes a bootloader that permits radio firmware upgrades over the serial interface, and radio firmware with configurable parameters. Firmware upgrades and configuration are fully supported in the APM Mission Planner. Configuration is also possible through AT commands.

 

Technical specification:

Light weight (under 4 grams without antenna)

Frequency: 433-434.79MHz

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)

Support for LBT and AFA

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

Adaptive flow control when used with APM

Based on HM-TRP radio modules, with Si1000 8051 micro-controller and Si4432 radio module
