STM32f103ZE High Performance Color Silk Screen Development Board

 


## Introduction

This project is a STM32f103ZE high performance color silk screen development board. Although it is only 10×10CM in size, it contains a wealth of peripherals and expansions! ! The board uses color silk screen printing technology. Who doesn’t want to have a good-looking development board? www?

supply adopts two sets of tyepc and lithium battery power supply solutions, which can be switched at any time. We can take the baby development board everywhere Run o(≧∇≦o)! !

> When the switch is turned OFF, it is powered by the battery

~~ I think the design of the power supply system is not perfect enough. The chip is extremely hot when the battery is charging. No boss can help me improve it~~~

##
The design of the peripheral module list interface refers to common, cheap and easy-to-use modules on the market, so you don’t have to buy those expensive modules!

## The circuit design of the pin configuration table
refers to the development board of the Battleship series, and the io configuration is basically compatible with the official routines.
The following is the pin configuration of the development board. With it, it will be much more convenient to transplant the configuration and so on!
![io port configuration table v2.png] ## Postscript
The development board has been used for a while, and the feeling of using a development board designed by myself is still very different!
Some minor problems were also discovered during this period, and all have been corrected. The project will continue to be maintained and updated in the future.
Finally comes the sticker file~
