Frequently asked questions
How do I program the STM32F405RGT6?
Use an SWD programmer such as ST-Link with an IDE like STM32CubeIDE or PlatformIO, or the Arduino core for STM32 boards. Check the pinout and debug connections in the datasheet before wiring.
Can I connect 5 V signals directly to its pins?
Not safely in general. The core runs from 1.8 V to 3.6 V, and not every pin is 5 V tolerant. Check the datasheet for each pin and use level shifting where needed.
