Description

Matek H7A3-WING flight controller is based on a powerful 280MHz STM32H7A3RIT6 processor, 1.4MB RAM and 2MB flash memory. The built-in ICM42688P IMU and SPL06-001 barometer provide accurate altitude control and stabilization during flight. Equipped with a large number of interfaces for connectivity, including 6 UART ports with built-in inversion, 11 PWM outputs, 4 ADC inputs (VBAT, Current, VB2, Cur2) and 1 I2C. The BEC 5V/4v5, BEC 9V/12V, and BEC Vx outputs provide reliable power for peripherals. The Dupont 2.54 pins are supplied unsoldered, which opens up the possibility of personalized configuration, which is easy to implement thanks to the 30.5*30.5mm mounting.
