Overview

This project refers to the project modifications of the brothers below↓↓
https://oshwhub.com/small_da/xuan-cai-hui-zhang-mu-kuai-BUAAb. The original intention is that in addition to USB power supply, the boards can be connected in series, so Made a reusable design. So what you need to pay attention to is the positioning hole of the USB port shell. Below are the positive and negative pads. Be careful of tin leakage! ! Take protection! !
