Product overview
The DolphinRC F405 80A FPV Stack provides flight-control electronics for an FPV aircraft build, with an STM32F405 controller, ICM42688P gyroscope, built-in barometer and AT7456E OSD chip. Its specified board measures 36*36mm, weighs 7g and uses a 30.5×30.5mm mounting pattern with 4mm apertures. Betaflight firmware support, a built-in 16M black box and USB Type-C connection form the core configuration. A BOOT key allows entry into DFU mode when held while USB is connected or power is applied.
Integration connections include soldered-wire or 6-pin cable options for a DJI Air Unit and GPS, four UART ports, and M1-M8 ESC signal outputs supporting 4-8 axes. Power input accepts a 4S-8S lithium battery through the rear 10-pin interface or GND and BAT pads. Eight 5V outputs share a 2A total limit, while two 12V outputs share a separate 2A total limit. Additional interfaces cover current sensing, camera alignment, Betaflight LEDs, a 5V passive buzzer and SmartPort through any serial-port TX.
