#The7thLiChuangElectricityCompetition#USB power meter

Overview

1. Project function introduction:
A voltage and current meter developed based on the National Technology N32G430C8L7 chip to measure the voltage and current flowing through the USB.

2. Project attributes:
2022 Summer Training Camp Course: Maximum measurement voltage: 6V Maximum measurement current: 2.8A Support power display

3. Open source agreement
GPL 3.0

4. Hardware part:
The reset circuit and BOOT selection circuit directly use two pads instead of 2P pins.

5. Software part: The software is written in KEIL5. STlink is used for program burning, and four external wires are enough.

6. BOM list

7. Competition LOGO verification

8. Demonstrate your project and record it as a video and upload it
