# Nanjing University of Posts and Telecommunications Automation Science and Technology Association 2022 Teaching Platform

## Introduction

This project is the Nanjing University of Posts and Telecommunications Automation Science and Technology Association 2022 teaching platform, which is used for the 2022 embedded teaching of the Science and Technology Association of the School of Automation and Artificial Intelligence School of Nanjing University of Posts and Telecommunications.

## To realize the function

master control, Xuantejia Electronics STM32F401CCU6 core board is used to lead out all IOs, and separately lead out the power supply, serial port, IIC, reserved IO or matrix keyboard and other interfaces, equipped with a 0.96-inch SPI OLED display, potentiometer, RGB LED lights, passive buzzers, buttons and other common peripherals.
The PCB silk screen has already marked the required resistor values, making it easier for novices to solder. The IO connected to the peripherals has been marked to facilitate program development.
**Note: The LDO and chip capacitors on the back of the board do not need to be soldered by default. If the core board's built-in LDO burns out, it can be used as a replacement. The switch connects the IO port and 3.3V and requires an on-chip pull-down. **
