The SpeedyBee F405 Mini BLS Stack integrates a high-performance flight controller and a reliable 35A 4-in-1 ESC into a single, compact unit. The flight controller is built around the STM32F405 microcontroller and an ICM42688P gyro, providing a stable and responsive flight experience for Betaflight and other flight firmware. Its integrated Bluetooth module eliminates the need for a physical USB connection for on-the-field tuning and configuration.
The accompanying 35A BLHeli_S ESC is designed for smooth, high-frequency operation on 3-6S LiPo batteries. It incorporates TVS diodes to protect against voltage spikes from regenerative braking and features a robust power stage for consistent current delivery. The dual BEC system offers flexible power routing, with dedicated 5V and 9V rails to support a wide range of digital and analog FPV video systems.
