Microcontroller STM32F411CEU6

The board based on 32-bit microcontroller STM32F411CEU6 from STMicroelectronics in UFQFPN48 package. Chip has 512kB embedded Flash memory, 128kB RAM and can be running with frequency at 100 MHz. Microcontrollers GPIO lines are available on extension pin headers with Arduino UNO standard.


Microcontrollers pins: PA0(A0), PA4(A2), PA5(D13) and PB5(D4) don’t be a 5V tolerant pins. They shouldn’t be supply with voltage exceeding 3.3V

USB communication

On board programmer compatible with ST-Link/V2-1 make possible programming and debugging of STM32F411CEU6 microcontroller. State of programmer is signalling by the bicolour LED D3 – correct connecting of programmer to PC is signalling by constant red colour of LED, communication between programmer and microcontroller by blinking red and green LEDs and orange LED colour indicates communication error.
