Questions
How big is the ProPrj 研电赛优利德显示屏与旋转编码器 2026-06-08 PCB?
It measures 45 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ProPrj 研电赛优利德显示屏与旋转编码器 2026-06-08 use?
16 parts, built around the EC11N1525405, PZ254V-12-18P and S8050. 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 ProPrj 研电赛优利德显示屏与旋转编码器 2026-06-08 KiCad files?
From the MuseLinn/Electronics-Competition repository on GitHub, at the commit this page was made from: the board is kicad/ProPrj_研电赛优利德显示屏与旋转编码器_2026-06-08.kicad_pcb and its schematic kicad/ProPrj_研电赛优利德显示屏与旋转编码器_2026-06-08.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ProPrj 研电赛优利德显示屏与旋转编码器 2026-06-08 design in my own project?
Its repository states no licence, so its author keeps all rights: ask MuseLinn before reusing the design.
