STMicroelectronics Nucleo Development Board for STM32 Microcontrollers NUCLEO-F103RB NUCLEO-F103RB Data Sheet

DocID025833 Rev 3

The STM32 Nucleo board is a low-cost and easy-to-use development platform used to 
quickly evaluate and start a development with an STM32 microcontroller in LQFP64 
package.

Before installing and using the product, please accept the Evaluation Product License 

Agreement from www.st.com/epla.

For more information on the STM32 Nucleo boards and to access the demonstration 
software, visit www.st.com/stm32nucleo.

Follow the sequence below to configure the STM32 Nucleo board and launch the demo 
software:
1.

Check the jumper position on the board, JP1 off, JP5 (PWR) on U5V, JP6 on (IDD), 
CN2 on (NUCLEO) selected.

2.  For correct identification of all device interfaces from the host PC, install the Nucleo 

USB driver available on www.st.com/ stm32nucleo, prior to connecting the board

3.  Connect the STM32 Nucleo board to a PC with a USB cable ‘type A to mini-B’ through 

USB connector CN1 to power the board. The red LED LD3 (PWR) and LD1 (COM) 
should light up. LD1 (COM) and green LED LD2 should blink.

4.  Press button B1 (left button).
5.  Observe how the blinking of the green LED LD2 changes according to clicks on button 

B1.

6.  The demo software and several software examples on how use the STM32 Nucleo 

board features are available on www.st.com/stm32nucleo.

7.  Develop your own application using the available examples.
