Frequently Asked Questions

How do I program the WeAct BlackPill STM32F411CEU6 board?

You can program the board using several methods. Connect via the USB-C port and use the built-in DFU bootloader with STM32CubeProgrammer. For debugging, connect an ST-Link V2 programmer to the exposed SWDIO and SWCLK pins. The board is also supported by the Arduino IDE with the STM32duino core and can run MicroPython firmware flashed via DFU. Ensure boot0 is set correctly for the desired mode.

What is the purpose of the two crystals on the board?

The 25MHz high-speed external (HSE) crystal provides the primary clock source for the microcontroller core and peripherals, enabling stable operation at 100MHz. The 32.768kHz low-speed external (LSE) crystal is dedicated to the Real-Time Clock (RTC) and low-power sleep modes, allowing for accurate timekeeping and wake-up events in battery-powered applications without consuming significant current.

Can I power the board externally without the USB connection?

Yes, you can supply power externally. The board includes a 3.3V voltage regulator. You can provide 5V power to the '5V' pin on the header or 3.3V directly to the '3V3' pin. Ensure the external supply is clean and within the specified voltage limits to avoid damaging the onboard regulator or the STM32 microcontroller. The USB port can be used simultaneously for communication.
