Flight Control Unit
Shark SkyBasic FCU
A compact flight controller built for UAV system integration
Onboard sensors, 5–22 V power input and a Raspberry Pi pinout for compatible single-board computers—all on a 23.2 g board.
Core functions on one board
SkyBasic FCU brings motion, heading and pressure sensing together with power, analog inputs and flight-control interfaces on one compact board.
This reduces the number of external modules and connections needed for common functions.
It is suited to UAV platforms, autonomous systems, R&D projects and custom embedded applications.
- Weight
- 23.2 g
- Operating voltage
- 5–22 V
- Operating temperature
- −20 to +85 °C
SkyBasic FCU can work with Shark GCS when the system uses it for ground control.
Direct 5–22 V power input
SkyBasic FCU can run directly from a 5–22 V battery without a separate external regulator for its primary power input.
This reduces the components needed in the power path of portable systems and UAV platforms. Direct connection applies only within the stated operating voltage range.
| Parameter | Value |
|---|---|
| Operating Voltage | 5V–22V |
| USB Power Input | 4.75V–5.25V |
Motion, heading and pressure sensing
The onboard Bosch BMM350 magnetometer removes the need for an external compass in many installations. It can support heading estimation and navigation in GNSS-assisted applications.
A BMI270 accelerometer and gyroscope and a BMP280 barometer complete the sensor set for attitude, heading and barometric pressure.
| Parameter | Value |
|---|---|
| Accelerometer | Bosch BMI270 |
| Gyroscope | Bosch BMI270 |
| Magnetometer | Bosch BMM350 |
| Barometer | Bosch BMP280 |
SBC connection through a Raspberry Pi pinout
SkyBasic FCU uses the Raspberry Pi pinout and supports the single-board computers listed below.
Support is limited to this list; other boards with the same pinout are not necessarily compatible.
- Orange Pi Zero 2W
- Orange Pi 3B
- Rock Pi 4
- Rock Pi 5
- Banana Pi M2 Zero
- Banana Pi M4
- Banana Pi M5
- Le Potato (AML-S905X-CC)
- Radxa Zero
- Radxa Zero 2
- La Frite (AML-S805X-AC)
The SBC determines processing capacity
SkyBasic FCU’s processing capacity depends on the single-board computer connected to it.
Analog sensor inputs
The 3.3 V, 5 V and 12 V analog inputs can connect devices such as temperature, pressure, light and pitot sensors. Electrical compatibility must be confirmed for each sensor.
- Temperature sensors
- Pressure sensors
- Light sensors
- Potentiometers
- Pitot tubes
