SpeedyBee F405 V3 BLS 50A

SpeedyBee F405 V3 BLS 50A 30×30 Stack

The SpeedyBee F405 V3 Flight Controller, with its advanced STM32F405 MCU and BMI270 gyro, is engineered for precision in the sky, further enhanced by its Type-C USB and integrated barometer. Designed for the modern FPV pilot, it features a seamless connection to DJI systems and customizable BetaFlight configurations via a user-friendly Bluetooth connection. A blackbox microSD slot, diverse power outputs, and multiple UARTs offer extensive data logging and peripheral support. Complementing this is the robust SpeedyBee BLS 50A 4-in-1 ESC, leveraging BLHeli_S technology to deliver consistent 50A power and surge protection, all controllable via the SpeedyBee app. This stack promises to be a reliable cornerstone for any custom drone build, prioritizing performance and ease of use.
