#The 7th Lichuang Electric Competition#USB-Ammeter

Note: * is a required item.
Please fill it out during the registration stage↓
 
* 1. Project function introduction
A small and useful USB ammeter based on the national chip N32G430C8L7
 
* 2. Project attributes The schematic diagram of
the LiChuang training camp
refers to the official case, and the PCB is independently drawn
 
 
* 3. Open source agreement
 
Please fill in the competition stage↓
 
* 4. Hardware part The main
 
control circuit
needs to pay attention to each power pin of the chip needs to be connected to an additional 100nF external filter capacitor, and the 1st pin of the chip needs to be connected to an additional 4.7uf filter capacitor.
 
The power supply circuit
uses a typical ldo AMS1117. Although the maximum input of this model is 15v, considering the high temperature, it is recommended not to exceed 8v. If you need to measure a larger voltage, it is recommended to use a dcdc current sampling circuit
 
 
* 5. Software part
 
It is recommended to use link to download. There will be many problems with serial port burning.
Remember to pull up the boot first and then power on the serial port burning
 
* 6. BOM list
 
 
 
 
* 7. Competition LOGO verification
Please upload the project picture containing the competition logo. The logo is printed on the PCB in the form of silk screen.
Click zip to download the competition logo! (Competition logo).zip
 
* 8. Demonstrate your project and record it into a video to upload.
 
Video requirements: Please shoot horizontally, with a resolution of no less than 1280×720, in Mp4/Mov format, and a single video size limited to 100M;
Video title: Lichuang Electric Competition: {Project Name}-{Video Module Name}; For example, Lichuang Electric Competition: "Autonomous Driving"-Team Introduction.
