XK-F303E Wireless Video and Data Link
XK-F303E combines network video, telemetry and remote-control data in a compact platform-to-ground radio. Xingkai specifies the radio configuration and accessories around your terminal equipment and intended communication layout.
- A 115 × 92 × 28 mm enclosure and device weight of ≤300 g give you a defined footprint and radio-weight budget for platform installation.
- Network data, UART telemetry and SBUS control can share the wireless link, with TTL or RS232 connections selected for the serial terminals.
- Point-to-point and point-to-multipoint relay configurations let the link arrangement follow your endpoint requirements.
- The catalogue-listed 18–30 V DC configuration lists air-unit and ground-unit consumption separately, helping you plan the two power supplies rather than treat them as identical loads.
XK-F303E Wireless Video and Data Link Overview
XK-F303E carries IP video, serial telemetry and control data over the same wireless link. Its compact enclosure provides a mechanical starting point for projects where the camera and control terminals are already selected and the radio must fit the remaining installation space.
The catalogue-listed configuration accepts 18–30 V DC and lists consumption as 10 W for the air unit and 18 W for the ground unit. Keep the two electrical budgets separate, and allow for antennas, cables and mounting components in the installed weight. The RF-output entry of ≤33 dBm is a different measurement from electrical consumption.
Xingkai checks the required terminal interfaces and communication layout, then identifies the supplied radio configuration, air-unit and ground-unit quantities and accessories in the quotation. Confirm the electrical requirements of that configuration before fixing the platform and ground-end supply arrangements.

Connections and Integration
Connect the onboard network-video source through Ethernet, flight or payload telemetry through UART TTL/RS232, and remote-control data through SBUS. At the ground end, the station exchanges data through serial or UDP/TCP network connections. This brings viewing and control paths into the planned platform-to-ground arrangement.
For the selected 18–30 V DC configuration, allocate 10 W to the air radio and 18 W to the ground radio. Keeping those loads separate helps size each endpoint’s supply alongside its connected equipment.

FAQs
Make two supply lists: one for the 10 W air radio and onboard devices, another for the 18 W ground radio and station equipment. Both radio inputs must suit the selected 18–30 V DC configuration. Give the actual output range and available capacity of any batteries or converters you intend to retain, and identify any supply equipment you need quoted. Size each endpoint for its connected devices as well as its radio.
Allow for an external network encoder between that camera and the radio. Its power and installation space are additional to the 10 W air-radio load and the radio’s own enclosure; the radio is not the camera’s complete power budget. Send the camera output format and any selected encoder details. Identify whether the encoder and its supply are already available or should be separately included in the quotation.
Check the exact units before reusing the supply. The F303E configuration here lists 18–30 V DC with 10 W air and 18 W ground consumption; the F303KE entry lists 12–28 V DC and ≤11 W at 33 dBm. Their listed enclosure dimensions match, but those electrical entries differ. Send the installed suffix, endpoint role, actual supply and link settings, and identify retained equipment so the proposed replacement configuration can be checked.
Specify the electrical level and the command path separately. The F303E lists UART TTL/RS232 for transparent serial transport and SBUS for remote-control data. Give the flight controller or payload model, its required serial settings and the operations you need at the ground station. If the equipment uses different command formats, identify the needed conversion separately before confirming the connection and accessory scope; do not assume the radio supplies that conversion.
Separate the platform installation list from the ground equipment. Count each onboard radio, antenna, cable and mounting component, then add the individual weights for that assembly. The ≤300 g entry describes device weight, not the complete installed system. Confirm the selected onboard components and their weights before allocating the platform payload budget or comparing radio options.
