Schematic

Microcontroller STM32F411CEU6

The board is equipped with a 32-bit microcontroller STM32F411CEU6 from STMicroelectronics. The system has a UFQFPN48 package, built-in 512kB Flash memory, 128kB RAM and can operate at a clock speed of up to 100 MHz. The GPIO lines of the microcontroller have been led out to pin sockets with a spacing compatible with Arduino UNO.

Attention! Microcontroller lines: PA0(A0), PA4(A2), PA5(D13) and PB5(D4) are not "5V tolerant" lines, do not apply voltages exceeding 3.3V

Power

The KA-NUCLEO-F411CEv2 board can be powered both from the USB port and using an external power supply with a 5.5 x 2.1 plug. The board has built-in protection against reverse power supply polarity. The built-in jumper allows you to select the supply voltage for Arduino Shields, giving you the option of setting the voltage on the VIO line at 5 V or 3.3 V.

USB communication

The programmer built into the board, compatible with ST-Link/V2-1, allows for programming and debugging the STM32F411CEU6 microcontroller. The programmer's operating status is indicated by the two-color D3 LED - correct connection of the programmer to the computer is indicated by the diode lighting up red continuously, data exchange between the programmer and the microcontroller is indicated by alternating flashing of the green and red diodes, while the orange color of the diode indicates an error in communication with the target system. The UART-USB interface built into the ST-LINK/v2-1 programmer can be disconnected from the microcontroller line using the [VCOM] D1/D0 OFF jumpers. The PRG-OFF jumper allows you to block the programmer, so that the operation of the STM32F411 microcontroller will not be disturbed by the programming interface.

Any purpose LED and RGB LED

The KA-NUCLEO-F411CEv2 board has two user diodes – the L13 diode (connected to the D13 line of the microcontroller) and the tricolor diode (whose cathodes are connected to the PB13...PB15 lines of the microcontroller); both can be controlled by the user program.

USB Host Connector

The microUSB connector built into the KA-NUCLEO-F411CEv2 board is connected to the microcontroller, so it can be used to support Full Speed USB devices.
