SIYI DK32S · CONTROL AND TELEMETRY

A dedicated UAV radio when live video has its own display

The SIYI DK32S is a 16-channel remote control and telemetry system for UAV integration. Its 2.8-inch capacitive touchscreen is used for controller settings and status. Choose it when the aircraft needs physical radio controls and a data link, while a separate computer, tablet or video system handles the larger mission display.

That distinction matters when comparing prices with a seven-inch Android ground station. DK32S has a different role: it does not turn its small configuration screen into a built-in HD camera monitor.

Choose the system from the aircraft outward

Match the aircraft control input
The published air unit offers 16-channel S.Bus and eight-channel PWM outputs. Start with the autopilot or control board's required input, then define the needed auxiliary functions. Channel availability and the assignment of switches are separate questions.
Define the telemetry connection
The air unit provides a UART data connection. SIYI lists PX4, ArduPilot and flight controllers supporting transparent UART communication as intended integrations. Supply the autopilot model and software version so the relevant wiring and protocol can be confirmed for your aircraft.
Choose an external mission terminal
DK32S supports USB and Bluetooth connections to computers and mobile devices. Decide whether the operator needs a laptop, phone or tablet for mission information. The terminal, application and any required cable or accessory should be named in the quotation.

Compact controller, separate airborne unit

Ground screen: 2.8-inch capacitive LCD; 240 × 320
Control system: 16 physical channels; 16 communication channels
Ground battery: Built-in 3.7 V, 5,000 mAh Li-Po
Charging: Micro-USB
Ground size and weight: 194.5 × 172.5 × 114 mm; 610 g
Air unit: 51.5 × 38 × 13 mm; 33 g, excluding antennas

The air unit specification lists a 5 V supply. Its voltage telemetry range is a separate measurement input specification; it is not permission to power the receiver from a higher-voltage aircraft battery.

Where DK32S makes sense

Consider DK32S for a multirotor or VTOL project in which the team already uses an external mission computer, or for a radio setup that needs reusable aircraft profiles. SIYI lists storage for 64 model groups, with expansion by SD card. This makes model selection part of the buying decision: identify the aircraft types and the different switch layouts the team intends to use.

If the requirement is an integrated camera image on an Android touchscreen, compare a dedicated video ground station instead. The SIYI MK32 addresses that different requirement. A smaller settings display should not be selected on the assumption that it replaces a large video screen.

The manufacturer's 12-hour endurance reference and 20 km unobstructed, interference-free range reference describe stated conditions. They are not FD field-test results or guarantees for a particular site. Confirm the proposed configuration and operating environment before comparing headline distances.

DK32S purchase questions

Does the touchscreen show the drone's live camera feed?

The listed 240 × 320 touchscreen is the controller's settings and status interface. Specify a separate video system and display if live camera viewing is required.

Is CAN included on every air unit?

SIYI identifies CAN as optional in the feature description. Request that exact version if your project requires CAN; the basic listed data interface is UART.

Is DK32S the same as DK32 SE?

This listing uses the DK32S model and its published specifications. A differently named agricultural version should be quoted separately rather than assumed to have identical hardware.

Build a DK32S quotation around your UAV

Tell FD the aircraft type, autopilot, required S.Bus or PWM inputs, telemetry method and external terminal. Include the number of aircraft profiles you expect to use and whether optional CAN is needed. We can identify the controller, receiver and accessories required for that configuration.
