The P-NUCLEO-USB001 is a development board designed to add USB connectivity to Nucleo boards, which are compatible with a wide range of microcontrollers from STMicroelectronics. With the P-NUCLEO-USB001, developers can easily implement USB-based communication interfaces in their projects, including USB device, host, or On-The-Go (OTG) modes. In this guide, we will cover everything you need to know to get started with P-NUCLEO-USB001.

Overview

The P-NUCLEO-USB001 board features a USB Type A socket and a USB FS Micro-AB connector, which can be used to connect the board to a microcontroller via the Nucleo-64 connector or a USB cable, respectively. The board also includes a programmable microcontroller, the STM32F072RB, which provides the USB interface and can be used to implement USB device, host, or OTG functionalities.

To use P-NUCLEO-USB001, you will need a Nucleo board, a computer running a USB host operating system (such as Windows, macOS, or Linux), and a compatible development environment, such as STMicroelectronic's STM32CubeIDE or STM32CubeMX.

Getting Started

To get started with P-NUCLEO-USB001, follow the steps below:

1. Connect the P-NUCLEO-USB001 board to a Nucleo board using the Nucleo-64 connector or a USB cable, depending on your application.

2. Install the necessary USB device/host drivers on the host computer, if needed.

3. Install the development environment, such as STM32CubeIDE or STM32CubeMX, on your computer.

4. Create a new project in your development environment and select the appropriate Nucleo board and STM32F072RB microcontroller.

5. Configure the USB interface mode and any other necessary parameters in your project.

6. Compile and build the project, and download it onto the Nucleo board.

7. Connect the Nucleo board to the host computer using the USB FS Micro-AB connector on the P-NUCLEO-USB001 board.

8. Test your application by using a terminal or other suitable software to communicate with the USB interface and exchange data.
