Betaflight F405 AIO Flight Controller — 35×35mm with OSD

The central brain of every custom FPV build. This Betaflight F405 all-in-one (AIO) flight controller integrates the STM32F405 processor, an on-screen display (OSD) processor, and a 4-in-1 ESC signal conditioner on a single 35×35mm board. Reduces build complexity, weight, and wiring by replacing three separate boards.

The F405 MCU runs Betaflight 4.x natively with full PID tuning, RPM filtering, bidirectional DSHOT, and GPS rescue support. UART ports provide connections for your VTX, receiver, GPS, and telemetry in parallel without conflicts. Built-in barometer for altitude hold and return-to-home on fixed-wing builds. Supported by Configurator GUI on Windows, Mac, and Linux.
