TELEMETRY DATA RADIO

Connect two known data endpoints

SIYI 2.4G Datalink is a compact radio option for carrying data between aircraft equipment and a ground endpoint. Its documented UART and USB connections are useful when the two devices and their software have already been identified. Describe that pair first, then select the radios and cables around it.

This product is a data link. It is not a handheld ground station, a screen for the operator or a camera-video system. A drone that needs both telemetry and an FPV image may require separate equipment for those two jobs.

Read the two speed figures in their own context

The catalog lists a 325kbps air data rate and a configurable UART baud rate, with 115200 as the default UART setting. These describe different parts of the connection. Neither should be treated as a guaranteed application throughput figure or as permission to carry an arbitrary video stream.

For a telemetry request, name the data source, intended receiving application and the information that must be exchanged. Ask the supplier to check the complete data path. A radio can carry a connection without establishing that the receiving software understands its contents.

Choose the ground connection deliberately

SIYI lists USB and UART data connections, with support described for Android phones and PCs. State the actual ground device and application rather than treating those platform names as a guarantee for every program. Include any required adapter or cable in the quotation.

Identify the aircraft endpoint separately

Give the exact equipment model and serial interface required on the aircraft. Ask for the compatible harness to be identified. A connector with the right shape does not, by itself, establish the required signal or software relationship.

Allow for antennas and the installed cable space

The catalog lists the ground radio at 50 × 35 × 16mm and 35g with its antenna excluded. Keep these ground-unit figures separate from the aircraft-side radio. Add antennas, cables and mounting provisions when assessing the complete ground setup and ask for the supplied air unit's dimensions separately. Bare-radio dimensions are not a complete assembly envelope.

The operating frequency is 2.4GHz. Request the supplied radio configuration appropriate to the intended market and use conditions. This description does not promise a particular operating distance; the radio and the actual installation should be assessed as a complete system.

SIYI 2.4G Datalink hardware detail and package reference — SIYI 2.4G Datalink hardware reference; pair or single-unit supply is agreed in the package.

Prepare a telemetry-specific purchase request

List the aircraft-side device, ground-side device, application, serial requirements and necessary radio quantity. Identify the cables, adapters and antennas already owned, then request the missing parts as a clear equipment list.

If the project also needs pilot control or live camera viewing, add those as separate requirements. This makes it possible to compare a small telemetry-only package with a broader control or video system without mixing their capabilities.

Data-radio questions

Does it include a pilot-control handset?

No. State any separate RC control requirement when specifying the ground system.

Can its air data rate be read as a video-stream rate?

No. The listed rate belongs to this telemetry radio, and this page does not claim a camera-video transport function.

Do the ground-unit dimensions include its antenna?

No. The 50 × 35 × 16mm and 35g ground-unit figures exclude the antenna; they are not specifications for both endpoints.
