Alphaswift FC Mini

The Alphaswift FC Mini is a compact, enterprise-grade flight control unit fully designed, developed, and produced by Alphaswift to support high-agility and extended-range UAV operations using 2S to 8S LiPo power systems. The FC Mini is compatible with leading autopilot ecosystems such as Betaflight, iNav, and ArduPilot, allowing seamless deployment across multiple aircraft configurations. The controller is driven by an STM32H743 microcontroller and utilizes a dual-redundant ICM42688P IMU architecture to ensure stable and precise attitude estimation, while an integrated Infineon DPS365 pressure sensor delivers dependable altitude information. An onboard analog OSD enables real-time video overlay, and flight logs can be stored locally via the integrated microSD card slot.

The Alphaswift FC Mini provides a comprehensive range of electrical interfaces, including up to 13 PWM outputs (LED incldued), 7 UARTs, 2 I2C buses, 1 CAN port, and 6 DEC inputs for voltage, current, RSSI, airspeed or secondary volatge/current measurement. High-voltage monitoring up to 69V is supported through the Vbat2. The board also supports 2 analog video sources with selectable input switching for flexible camera configurations. Power regulation is handled by an onboard 5V / 2.5A BEC, along with an auxiliary output 5V / Vbat (up to 2A) to power external devices such as FPV cameras or video transmitters. System setup and firmware access are provided via a USB-C interface, with additional solder pads available for an externally mounted USB connector. All electronic components are placed on a single side of the PCB, leaving the opposite side flat to reduce stack height and simplify installation in space-constrained platforms.
