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. It’s available in 433Mhz, and in the following configurations: serial board (for the air) and USB (for the ground).
Specification:
- Very small size
- Lightweight (under 4 grams without antenna)
- Available in 900MHz or 433MHz (v2 only) 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)
- 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 kilometres 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
