2. Working frequency: 433Hz

3. Receiving sensitivity: -121dBm

4. Transmission power: 20DBM (100 mW)

5. Transparent serial links

6. Air data transfer rate is as high as 250Kbps

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
