Creating a Custom Board Config in Arduino IDE

The Arduino IDE makes it surprisingly easy to program microcontrollers that aren’t part of the Arduino ecosystem—like STM32 devices. This is a useful feature for my project with the Matek H743 flight controller, which runs on an STM32H743 chip. It’s not a typical development board, but with a bit of extra effort, I’ve managed to get it working. Handling DFU Mode Programming an STM32 board isn’t as…
