The HAKRC F405 + 65A V2 flight stack: an STM32F405 controller with ICM42688P and a 4-in-1 speed controller at 65 A (75 A peak), 5 V and 9 V BEC.
The stack consists of an STM32F405RGT6 flight controller (ICM42688P gyro, BMP280 barometer, AT7456E OSD) and a speed controller at 65 A per channel with a 75 A peak for up to 10 seconds. The power section on low-resistance MOSFETs reduces heating, and the 5 V / 3 A and 9 V / 2.5 A BEC outputs power analog and digital video transmitters without extra modules.
Betaflight and INAV firmware are supported (target HAKRCF405), supply is 2–6S LiPo. Mounting is 30.5×30.5 mm and the stack weighs 25.5 g; convenient solder pads simplify soldering.
