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.
