STM32F411 "BlackPill" Development Board
This 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 backflow. There are both 25Mhz 9pF high-speed and 32.768Khz 6pF low-speed crystals on board.
This dev board is suitable for advanced users with STM32 development experience, we do not have a detailed tutorial usage for it.
