#The 7th Lichuang Electric Competition#USB voltage and current meter based on the main control STC8H1K17

* 1. Project function introduction:
USB power meter based on master control stc8h1k17 sampling INA180, which can detect the voltage and current of the main circuit, D+, D- voltage, display running time, real-time power, and power flow statistics, with a button to clear running time and power statistics.
Parameters: working voltage 4.5V-24V
           maximum design current 6A (unverified and no device)
