Questions

How big is the CurtainDrive V3 2 2L修改版 PCB?

It measures 102.5 × 71.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the CurtainDrive V3 2 2L修改版 use?

157 parts, built around the ESP32-S3-DEVKITC-1-N8R8, SN74LVC08APWR-TP, EL817S1(C)(TU)-VG and SN74LVC14APWRG3. 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 CurtainDrive V3 2 2L修改版 KiCad files?

From the LLAB1234567890/PCB- repository on GitHub, at the commit this page was made from: the board is project/CurtainDrive_V3_2_2L修改版.kicad_pcb and its schematic project/CurtainDrive_V3_2_2L.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the CurtainDrive V3 2 2L修改版 design in my own project?

Its repository states no licence, so its author keeps all rights: ask LLAB1234567890 before reusing the design.
