Description
Even on V3.1 boards do not try to use PB4 without redefining it as Pout and a low before trying to use it. Maybe,a note in the README.md not use this pin along with PA4, PA5, PA6 and PA7.

stm32/boards/WEACTV20_F411: Add support for WeAct v2.0 'blackpill' board
The WeAct v2.0 board (also sometimes known as the "blackpill") is a micropython-capable board based on the STM32F411CE (512kB flash, 128kB SRAM) that costs only a few US dollars and is widely available from various Chinese suppliers. It is a breadboard compatible breakout-style board that has reset/BOOT0/user switches, a user LED and a USB C connector, along with 25MHz and 32.768kHz crystals.
Although the board has an unpopulated flash footprint, I don't have any SPI flash ICs around to test it and add support, so this only supports internal flash for the time being. I have ordered some and will try to test the external flash when I get a chance.
