STM32 Nucleo-64-P boards (MB1319)

Introduction

The STM32 Nucleo-64-P boards based on the MB1319 reference board (NUCLEO- L412RB-P, NUCLEO-L433RC-P and NUCLEO-L452RE-P) provide an affordable and flexible way for users to try out new concepts and build prototypes with the STM32 microcontroller and the external SMPS (switched mode power supply), which provides various combinations of performance, power consumption and features.

ARDUINO® Uno V3 connectivity and ST morpho headers provide an easy means of expanding the functionality of the Nucleo open development platform with a wide choice of specialized shields.

The STM32 Nucleo-64-P boards do not require any separate probe, as they integrate the ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo-64-P boards come with the comprehensive free STM32 software libraries and examples that are available with the STM32Cube package.

UM2206	Quick start

5 Quick start

This section describes how to start a development quickly using the STM32 Nucleo-64-P board.

Before installing and using the product, accept the Evaluation Product License Agreement from the www.st.com/epla webpage.

5.1Getting started

The STM32 Nucleo-64-P board is a low-cost and easy-to-use development kit to quickly evaluate and start a development with an STM32 microcontroller in QFP64 package. To start using this board, follow the steps below:

1.Check the jumper position on the board, as shown in Table 4: Default jumper settings.

2.For a correct identification of all device interfaces from the host PC, install the Nucleo USB driver available on the www.st.com/stm32nucleo webpage, prior to connecting the board.

3.To power the board connect the Nucleo-64-P board to a PC with a USB Type-A or USB Type-C® to Micro-B cable through USB connector CN1. As a result the green LED LD3 (5 V PWR) lights up, LD1 (COM) and green LED LD4 blink.

4.Press user button B1 (blue).

5.Observe that the blinking frequency of the three green LEDs LD4 changes, by clicking on the button B1.

6.The software demonstration and the several software examples, that allow the user to use the Nucleo features, are available at the www.st.com/stm32nucleo webpage.

7.Develop an application using the available examples.

6.2.1Default board configuration

By default the STM32 Nucleo-64-P board is delivered with the external SMPS 1.1 V enabled and VDD@3.3 V. It is possible to set the board for VDD@1.8 V. Before switching to 1.8 V, the user should check that the extension module and the external shields connected to the Nucleo-64-P board are 1.8 V compatible.

The default jumper configuration and VDD@1.8 V setting is shown in Table 4.
