Speedybee F405 is an affordable AIO board with rich features, integrating flight controller with ESCs. The board can be powered by 3-6S Lipo batteries and is suitable for 3-4" drones, Cinewhoops and lightweight 5" drones. The aluminum heat sink helps dissipate heat and protects sensitive components from dirt. The flight controller is based on the F405 processor combined with the ICM42688P gyro. These are complemented by a barometer for altitude measurement and 8MB memory for the blackbox. The board can be set up via the integrated USB-C connector, external USB-C connector or integrated Bluetooth module. The board also includes a 5V BEC. The 9V BEC is not integrated, but is supplied separately for external connection. There are I2C pins on the board for compass connections. The controllers use Bluejay firmware and can handle current up to 40A.
