Micoair743 schematic

Hello everybody,

I’m looking for the schematic of Micoair743 (Ardupilot) for my own project.
If you don’t have the schematic, do you know how sensors connected to the Stm32H743 (interface: Spi, i2c,…; GPIO): IMU BMI088, BMI270, compass IÍt8310, baro DPS310.

Thank you.

Do you see that on the Open Hardware list?
Ardupilot Flight Controllers

Hello Dave,

I ‘ve found this document but don’t know which pins from the MCU Stm32h7 connect to the sensors. MicoAir743 — Copter documentation

I don’t use Ardupilot, I config the MCU on CubeIDE for my own project. Based on document ans testing, I can only find 3 pins for RGB leds and Uarts4,8. Other pin I don’t know how to config.

Thank you.

Hi Tan,

Microair lists the microcontroller’s pin use of this board on their product page. Check the Pinout tab.

To see how Ardupilot assigns pins for this board (or any other supported board) you can take a look at the relevant hwdef.dat on GitHub.

If you’re developing your own thing independent of Ardupilot, the pinout tab on the product page will be an easier reference.

Hello Muhammad,

This is exactly what I looking for. Some how I miss pinout tab.

Thank you so much.
