实物
更新注记
V1.0.0
实现了最基础的电压、电流、功率的读取和显示
V0.0.1
这个版本是最初的版本，具有我能够塞入的所有功能，结果发现嘉立创免费打样只支持0.3mm的孔，导致没有办法低价进行生产，随放弃，删除大量功能，只保留了最基本的功能，做出了 V1.0.0 版本

Questions
How big is the UsbMeter PCB?
It measures 17.5 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the UsbMeter use?
76 parts, built around the CH340E, W25Q128JVSIQ, W25Q32JVZPIQ and LP5912-3.3DRVR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the UsbMeter KiCad files?
From the TheBadZhang/usbMeter repository on GitHub, at the commit this page was made from: the board is hardware/usbMeter0/usbMeter.kicad_pcb and its schematic hardware/usbMeter0/ch217x.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UsbMeter design in my own project?
Its repository states no licence, so its author keeps all rights: ask TheBadZhang before reusing the design.
