 Now I want to introduce you the hard way which we will use for our hands-ons and It's the STM32 nuclear in my case I will use the STM32F401RE nuclear board and What we can found on this board? On this board in the middle of the board we can found the STM32F401RE But there are also other components Then we can found here the blue button which is connected to the PC413 and we can use it in our for our applications The black button is the reset button in case that you want to start the program again You can press the reset button and Then is the green LED which is connected to pin PA5 On the left and right side. There are also headers There are connected all three pins of the microcontroller They are directly connected to these headers Then you can use it to connect your own application your own external devices or you can connect here the our our extension shields There is also the second line of the headers Where you can connect the Arduino extension add-ons or also our XNUCLAW extension shields On the top part of this board you can found the stealing stealing debugger Which also can work as a master edge programmer when you drag and drop the binary Into this master edge which appear into your in your system And it will automatically program the STM32 There is also the virtual comport bridge between the USB and UART which is directly connected into STM32F401 And the main part is the debugger which can be used for the programming or debugging of our application It's run over SWD interface Don't forget not over JTAG over SWD And you can also connect the external devices if you unconnect these two jumpers You can use this connector to connect any external STM32 microcontroller Where you need to use some pins of this of this header Mainly the clock SW clock the ground and SW data. This is the minimum settings Setting we recommend also to connect at least the reset and the last part how to connect this board to your PC for this We use this USB connector in my case it is mini USB connector in case that you have STM32 Nuclear board with 32 pin or the 144 pin nuclear you will have the Micro USB connector The board is also powered from this connector Then it must be plugged into your PC all the time If you want the better description of the all your features and also schematics You can found it in the user manual from the nuclear which is on our websites It's called the UUM 1724 or here in the external link Is the link on our website where you can download this manual?
