Nucleo f401re development arduino serial#

The board has internal oscillators of 16MHz and 32KHz. The IOREF pin is only one in the whole board and it common with Arduino pins. It will allow the board to operate according to 3V. In case of using the 3.3V for power up the device, the IOREF pin should be active. The 3.3-volt pins are connected through regulators. The other 5V and Vin pins in all headers can be used for 5V. VBAT and E5V have protections and only for input. The boards’ givens the power outputs of 5V and 3.3V all the 5V outputs are connected directly expect VBAT and E5V. The power pins on Nucleo F401RE and Arduino are: The STM32 board can be turn on by using the 3.3 and 5V but the whole board can only power up through 5V. There are multiple power input pins for both boards. There are multiple power pins and method to power up the board and all of them are: Power Input VREP – GPIO8 Power Pin of STM32 Nucleo F401RE.The analog reference voltage pins are available for STM32 and Arduino too. STM32 Nucleo F401RE allows the developer to add the analog voltage reference by which ADC will be able to measure the input value. The ADC allows the external voltage to convert the analog signal to digital. All these channels are 12-bits and they exist in both types of header. There are a total of 16-channels of A/D on the board. SDA – GPIO9 STM32 Nucleo Analog to Digital Converter Channels.In STM32 Nucleo F401RE both types of headers support I 2C communication. These pins can communicate with external I 2C modules. It is based on two pins with a clock and a data pin. There are multiple pins for I 2C protocol. In Nucleo F401RE has multiple SPI pins which are: Multiple devices of the same kind can be controlled by a single SPI module. Two for clock and device selection and two for data.

SPI protocols are also a kind of serial communication that uses four-wire for communication. The UART on Arduino only allows communicating a single UART device. All these pins allow the multiple UART module to communicate with the board at a time. There are multiple UART communication pins in the Nucleo F401RE. D11 – GPIO12 Serial Communications in STM32 Nucleo F401RE UART Communication Pins.These PWM pins use a Prescaler to break the single cycle of the clock pulse to generate the output signal. All PWM pins can generate the desired output signal to control the external peripherals. PWM pins are available in both STM32 and Arduino.
