硬件设计
- 下载按键需要超级小的两脚小龟按键，如果不重复下载调试，可以不焊
- 整体需要包热缩管进行绝缘，不然手汗会造成数据异常

Questions
How big is the Daplink CH552P PCB?
It measures 30.4 × 12.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Daplink CH552P use?
21 parts, built around the CH552G, SN74LVC1T45DBV and RT9193-33GB. 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 Daplink CH552P KiCad files?
From the abgelehnt/Tiny-DAPLink repository on GitHub, at the commit this page was made from: the board is 1.Hardware/Daplink_CH552P/Daplink_CH552P.kicad_pcb and its schematic 1.Hardware/Daplink_CH552P/Daplink_CH552P.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Daplink CH552P design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
