To power the board we can either use the USB port or directly provide regulated 5V to the E5V or to the 5V pin here. Then we have a reset button here and a user-configurable button that is connected to pin PC13 and also an LED here which is connected to pin D13 just like Arduino. The other males are called ST morpho pins which can be used to utilize the reaming pins on our 64-pin microcontroller.
The board has two sets of connectors, the female pins are for Arduino shields which perfectly fit our ESP8266 Wi-Fi Shield and our Semtech Arduino LoRa Shield as you can see in the image below. Now here comes the interesting part, as I told you earlier the board supports all Arduino shields. You can check the STM32F401 Datasheet to get more technical information. It also has three USART, three I2C, four SPI and one USB 2.0 for external communications. The Microcontroller has 10 timers of 16-bit and 32-bit and a single 12-bit ADC. This is a 64-Pin 32-bit Microcontroller with an ARM Cortex M4 processor operating at 84MHz. Moving down to the development section we have our most important component here, the STM32F401RET6 Microcontroller. Over here we have a Tricolor LED (LD1) which turns on as Red when the board is powered and turns to green when the board is successfully programmed and turns orange when there is a communication failure. And this connector pin JP1 can be closed to limit the USB current to 100mA, if left open the maximum current will be 300mA. In the future, you can remove these jumpers to use the programmer for other ST microcontrollers through these pins. The two jumpers on CN2 are used to connect the programmer and debugger section with our development board. On the first look, the board might seem to have a lot of jumpers and components, but they all are there to make things easy for us. The Two jumpers that you find either side of the board CN11 and CN12 are actually dummy jumper, these jumpers can be used for other purposes if needed in the future. This way you can easily program and debug your board out of the box just with an additional USB cable that can be connected to the USB mini port on the board. The top section is ST-Link /V2 debugger and programmer while the bottom section is your actual development board. Taking a closer look at the board we can find that the board is divided into two regions.
NUCLEO F401RE EXAMPLE CODE HOW TO
The instruction card mentions the specifications of the controller, its pinouts, and on the backside, we have some information on how to get started and available toolchain options. As you can see the complete package only consists of our development board and an instruction card. Let's begin by unboxing our Development Board. STM32 Nucleo 64 Development Board Hardware Explanation Similarly, there are many other versions of Nucleo 64 boards like the STM32F103, STM32F303, etc, but once you learn about one board all the others are quite similar. The name STM32 represents that we have a 32-bit Microcontroller on our development board, and the name Nucleo-64 represents that the microcontroller has 64 pins. Now there are many versions of STM32 boards available and this particular one in my hand is called the STM32F401 Nucleo-64. So in this article, let’s take a complete look at this STM32 Nucleo-64 Development boards and learn how to use them. Also getting familiar with an STM32 Microcontrollers will help you to easily explore other development modules from ST like the SensorTile.Box which we reviewed earlier.
NUCLEO F401RE EXAMPLE CODE SOFTWARE
This process can be made a lot easier with this STM32 development board as it can support all Arduino shields to help you on the hardware side and also has many built-in libraries and functions to help you on the software side. But, like as well all can agree, your Arduino could take you only so far and someday you have to move to a native microcontroller platform. For most people out there, the first embedded development board that they would have worked on would most probably be an Arduino Board.
