Compact UAV integration
Keep the flight controller small without losing the ports you need
The SIYI UniFC 6 PICO suits a compact drone project when a small enclosure, Ethernet and a broad peripheral interface set matter together. The catalog lists a 40g controller measuring 49 × 42.6 × 16.2mm. Treat that as the controller envelope: allow additional room for plugs, cable bends and the selected mounting arrangement.

Start with the board envelope
A small controller can free space in a civil FPV, multirotor or fixed-wing installation. Compare the enclosure against the usable electronics bay rather than the aircraft's overall dimensions. The connectors sit on several edges, so a board that fits on paper still needs an accessible route for its cables.
Compare the sensor platform
The STM32H743IIK6 processor is listed at 480MHz with 2MB flash and 1MB RAM. The supplied specification names ICM45686 and BMI088 IMUs, two ICP20100 barometers and IMU heating. These describe the hardware platform; they are not evidence of a particular aircraft's navigation accuracy or an independently certified redundancy level.
Reserve the useful connections
The 100Mbps Ethernet port is a reason to consider PICO where network-connected equipment belongs in the project. Five UART ports, three I2C interfaces and two CAN buses provide other peripheral choices. Prepare a list of the actual devices you intend to use so the proposed package can be checked against those connection types.
| Project requirement | Catalog interface to review | What to identify in the enquiry |
|---|---|---|
| Navigation receiver | CAN or the appropriate serial connection | The GNSS model and supplied harness |
| Actuator connections | 14 PWM outputs; 3.3V/5V levels listed | The intended signal-level requirement |
| Ground access and records | Type-C USB and TF card slot | Access space, cable and storage requirements |

Choose the firmware and package together
SIYI lists compatibility with the ArduPilot and PX4 ecosystems across several vehicle types. Name the civil aircraft type and the software release needed for your project. Request confirmation of the controller revision, selected firmware support, GNSS option, cables and mounting parts. For repeat builds, retain the same identified package so a later order is easy to compare.
UniFC 6 PICO buyer questions
- Does the small size mean it is only for FPV aircraft?
- No. The catalog also lists multirotor, fixed-wing and VTOL applications. Aircraft and firmware compatibility still need to be checked for the selected project.
- Is a GNSS module included?
- It depends on the chosen package. The controller and a GNSS combo should be identified separately in the quotation.
- What should accompany a request for this controller?
- Send the available mounting space, aircraft type, firmware requirement and a list of peripherals. These are more useful for selection than a controller-only model name.
