ST STM32 Nucleo User manual

Introduction
The STM32 Nucleo-64 board, based on the MB1717 reference board (NUCLEO-C031C6 order code) provides an affordable
and flexible way for users to try out new concepts and build prototypes with various combinations of performance, power
consumption, and features.
The ARDUINO® Uno V3 connectivity support and the ST morpho headers provide an easy means of expanding the functionality
of the STM32C0 Nucleo open development platform with a wide choice of specialized shields.
The STM32 Nucleo-64 board does not require any separate probe, as it integrates the ST-LINK/V2-1 debugger/programmer.
The STM32 Nucleo-64 board comes with the comprehensive free STM32 software libraries and examples that are available with
the STM32CubeC0 MCU Package.

5Quick start
This section describes how to quickly start development using NUCLEO-C031C6.
To use the product, the user must accept the Evaluation Product License Agreement from the www.st.com/epla
webpage.
For more information on the STM32 Nucleo-64 board and demonstration software, visit the www.st.com/
stm32nucleo webpage.
5.1 Getting started
Follow the sequence below to configure the STM32 Nucleo-64 board and launch the demonstration application
(Refer to Figure 3 for component location):
1. Check jumper positions on board: CN2 ST-LINK [1-2] and [3-4], JP5 PWR [1-2], and JP6 ON.
2. For correct identification of all device interfaces from the host PC, install the Nucleo USB driver available on
the www.st.com/stm32nucleo web page, before connecting the board.
3. To power the board, connect the STM32 Nucleo-64 board to a PC with a USB Type-A or USB Type-C® to
Micro-B cable through the CN1 USB connector. Once powered on, the LD3 PWR green LED lights up and
LD1 COM LED blinks.
4. Press the B1 blue user button.
5. Observe that the blinking frequency of the LD4 three green LEDs changes, by clicking on the B1 button.
6. The demonstration software and several software examples showing how to use the STM32 Nucleo features
are available from the NUCLEO-C031C6 product location.
