Description
- The 3DR Radio Telemetry of 3D Robotics is an ideal module to set the remote sensing connection module between APM and ground station.
- It features small volume, cost effective, wider transmission range, and it allows us to do things that other radio modules can’t do.
- Compared with other radio, this 3DR radio telemetry has the following merits: 1.Very small volume
- 2.Selectable operating frequency: 915MHZ 433HZ 3.Receiving sensitivity: -121 dBm 4.Transmission power :20 DBM (100 mw) 5.Transparent serial links 6.Air data transfer rate is as high as 250 KBPS
- 7. MAVLink frame protocol and status report 8. Frequency-hopping spread-spectrum (FHSS) 9. Adaptive Time Division Multiplex (TDM) 10. Support LBT and AFA
11. Configurable duty ratio 12. Built-in error correction code (can correct up to 25% of the data error) 13. Transmission range can reach miles with the small Omni-directional antenna 14. Use bilateral amplifier to gain greater scope 15. AT command deploys data transmission 16. RT command remotely deploys data transmission 17. self- adapt to the flow control when used with APM 18. Based on HM - TRP wireless module, equipped with Si1000 8051 micro controller and the Si4432 radio module. 19. The Master collocates with long antenna and the Slave collocates with a short antenna to reduce the load of the aircraft.
