#The 7th Lichuang Electric Competition#Desktop power control board with pd

Note: * is a required field,
please fill it out during the registration stage↓
 
* 1. Introduction to project functions
The main function monitors the input and output current and voltage (0-30V, 7A fuse), and can be used to spoof voltage through typec. The pfc cable is used to control the buck-boost module I already have, which can be left blank in this project. The XT60 at the input end conflicts with the terminal block, but it is left for the convenience of expansion.
 
Note: The topic is not limited, it can be a solution to a problem in life/work, a solution designed for a certain group of people/scene, a graduation project/course design/DIY project/purely cool project, etc. Mainly talk about what means you used to solve what problem.
 
*2. Project attributes
The project is open to the public for the first time and is based on the expansion of existing projects.
 
Note: Please indicate whether the project is open to the public for the first time; whether the project is original; whether the project has won awards in other competitions, and if so, describe the details of the award; whether the project has participated in the defense at school.
 
* 3. Open source agreement
GPL3.0
 
Note: Altruism is self-interest, please read the following content carefully.
Embrace open source and give the project unlimited value. It is recommended that more than 80% of the core functions of the project be open source;
if a part of the function is irreplaceable and the project cannot solve the corresponding problem after deleting it, then the function implemented by this part is the core function of the project; for example, if an electronic load is designed and a host computer software is designed to monitor power changes, the electronic load is the core function and the host computer software is an auxiliary function; for example, an isolated 485 module is used in the electronic load to communicate with the host computer, then the communication function implemented by this 485 module is an auxiliary function;
the project should choose an open source protocol that suits it. If the project references other open source projects, the source should be indicated and the original author's open source protocol should be followed; the original project is recommended to use the GPL3.0 open source protocol;
the functions implemented by directly quoting the original circuit or original code of the open source project cannot be used as the core functions of your own project, and the functions directly implemented by using the general modules on the market cannot be used as the core functions of your own project.
 
Please fill in the following in the competition stage↓
 
*4. The hardware part
uses INA199B1DCKR to detect the circuit current, the resistor divider to detect the voltage, and reads and displays it on the oled through n32g430adc. In addition, the CH224K chip is used to control the different voltage outputs of the charging head.
 
Note: It is recommended to use Jiali Chuang EDA. If you choose other EDA tools, please upload the schematic diagram in PDF format, the PCB drawing in PDF format, and the PCB file in Gerber format in the attachment. Here you can explain in detail the implementation principle and mechanism of your project, precautions, debugging methods, testing methods, etc. It is recommended to introduce your ideas to others in the form of pictures and texts.
 
*5.
See the attachment for the software part, based on keil5+stlink
 
Note: If your project involves software development, please upload the corresponding engineering source code in the attachment. Here you can explain in detail your software flow chart, functional module block diagram, explanation or popular science of related algorithms, source code structure, compilation environment construction and configuration, source code compilation method, program burning method, etc. It is recommended to introduce your ideas to others in the form of pictures and texts.
 
*6. BOM list
 
Note: BOM list involved in the project. Please upload a screenshot of the BOM in this position. Please upload the list details in the attachment in PDF format. It is recommended to include model, brand, name, package, procurement channel, purpose, etc. The specific content and form should be based on the clear expression of the project composition.
 
*7. When the competition LOGO verification
board arrived, I found that there was no logo printed on it. Please upload the project picture containing the competition logo. The logo is printed on the PCB in the form of silk screen.
