Matek H7A3-Slim is a flight controller designed for Ardupilot firmware. It uses a powerful STM32H7A3 processor, ICM42688P gyro, SPL06-001 barometer. There is 128MB of memory for data logging. The board has six UARTs, one I2C bus, one CAN bus, four ADC inputs (VBAT, Cur1, VB2, Cur2), eleven PWM outputs, and both 5V and 9V BECs. The 9V BEC is switchable, which will come in especially handy for powering video transmitters. The board can be powered in the range of 3-36V (2-8S Lipo). The board has components on only one side, which makes it easy to install.
The flight controller supports Ardupilot firmware only.
