SpeedyBee F405 AIO 40A Flight Controller
All-in-one flight controller with an integrated 40A 4-in-1 ESC — built for 2–4 inch (and ultra-light 5 inch) FPV drones on 3–6S.
STM32F405 MCU and ICM-42688P gyro deliver stable, responsive flight. Bluetooth 2.0 wireless tuning lets you configure and update firmware from the SpeedyBee app with no physical BOOT button, while the DJI Sky Port gives direct 6-pin connection to HD systems. Compact 25.5×25.5 mm whoop mounting and a generous BEC set make it an easy drop-in for digital or analog builds.
Highlights
- STM32F405 MCU paired with the ICM-42688P gyro for crisp, reliable attitude control.
- Integrated 40A 4-in-1 ESC — continuous 40A, burst 45A (10s), supports DSHOT600 / DSHOT300.
- Bluetooth BLE 2.0 wireless tuning: adjust parameters, flash firmware and trigger BOOT from your phone — no boot button fumbling.
- 8 MB onboard Blackbox flash for flight logging, no extra hardware required.
- DJI Sky Port: plug DJI O3 Air Unit, RunCam Link or Caddx Vista straight in via 6-pin — no wire reordering.
- Flexible power: two 4V5 outputs (1A), three 5V outputs (2A, shared with 4V5), plus an external switchable 5V/9V BEC module (2A).
- Four full UARTs (UART3 / UART4 / UART5 / UART6 + SBUS) for GPS, receiver, HD system and more.
- Compact 25.5×25.5 mm whoop mounting (2 mm holes); board is 33×33×8 mm and weighs 13.6 g with CNC.
