Description

STM32F411 Black Pill Board 100MHz 128K RAM

This simple development board for the STM32F411 is a great way to add a powerful STM chip to your next project. Featuring the STM32F411CEU6, this chip has 512 KB of flash, 128 KB of SRAM, and runs at 100 MHz. There's a spot on the bottom for SOIC flash memory - you could solder on a 2 MB SPI flash memory chip to give yourself more space for datalogging or file storage.

STM32-F411-CEU6-MOD-003

The board features a USB C connector, with a 3.3V 100mA LDO regulator. There are both 25mhz and 32.768 KHz crystals on board. There's a few handy buttons: a BOOT button for entering the ROM DFU bootloader, a reset button, and a generic button on PA0 for users. One power LED and one user-controllable LED on PC13.

The chip itself has multiple UART, I2C, SPI, I2S, and timer peripherals. The USB is full speed. There's a single ADC multiplexed to 10 inputs.
