Product overview
The Holybro Kakute F405-Wing Mini combines an STM32F405RGT6 processor with an ICM-42688P inertial sensor, SPL06 barometer, AT7456E OSD and 128Mbits of onboard Blackbox storage. Its compact hardware measures 25 x 30 x 20 mm, uses 20 x 20mm mounting with M2 holes, and weighs 17g with the USB extension board. A USB Type-C USB/DFU key extender supports connection access, while separate blue and green LEDs indicate flight-controller status and the 3.3V supply.
For aircraft integration, the controller provides five UARTs, seven PWM outputs, two ADC inputs and one I2C interface. R3 includes inversion, PWM7 defaults to NeoPixel LED use, and external I2C devices share I2C2 with onboard sensors. The power board accepts 7.4~ 36V from a 2~ 8S LiPo and provides two ESC power pads. Its peripheral and servo BEC outputs each support 3 Amps continuously and 4.8A peak; the servo supply defaults to 5.3V, with 7.2V selectable through a jumper pad.
