H7A3-WING Flight Controller for Fixed-Wing & VTOL Meet the big brain for your wings: the H7A3-WING flight controller. Built around an STM32H7 processor, it’s made for INAV and Ardupilot pilots who push their fixed-wing or VTOL builds harder than their thumbs allow. Keywords: H7A3-WING flight controller, INAV fixed wing FC, Ardupilot VTOL FC. Why You Want It Because your flying wing deserves more than recycled quad gear. With the H7 chip, onboard OSD, barometer, and tons of UARTs, the H7A3-WING brings precision and processing power. Translation: smoother flights, more sensors, and fewer “why did it roll over?” moments. (Pilot error not excluded.) Specifications MCU: STM32H7A3RIT6, 280MHz Cortex-M7, 1.4MB RAM, 2MB Flash IMU: ICM42688P Baro: SPL06-001 OSD: AT7456E Blackbox: MicroSD socket I2C digital power monitor 6x Uarts (1,2,3,4, 5, 6) with built-in inversion. 11x PWM outputs 1x I2C 1x CAN 4x ADC (VBAT, Current, VB2, Cur2) 3x LEDs for FC STATUS (Blue, Red) and 3.3V indicator(Red) USB/Beep Extender with Type-C(USB2.0) 2x JST-GH1.25_4pin connector for CAN and I2C 9V/12V output ON/OFF switchable Digital video OSD is supported by any spare UART Regulators Vbat Input: 9~30V (3~6S LiPo) BEC 5V/4v5: 2.5A cont. /3A peak BEC 9V/12V: 2A cont. /3A peak BEC Vx: 8A cont. /12A Peak, output 5V Default, 6V or 7.2V option.
