STM32F411 "BlackPill" Development Board _MAKE_MODULE_GPIO Designed and assembled in theThis compact STM32F411 development board can be well embedded in your projects. Featuring the STM32F411CEU6, this chip has 512KB of ROM, 128KB of SRAM and runs at 100MHz. There is a spot on the bottom for SOIC flash memory, which allows you to solder SPI flash memory to give yourself more space for data logging or file storage. The board features a Type C connector and a 3. 3V 100mA LDO regulator. Also, a diode is connected in series to prevent power
