Questions

How big is the REV0.0.1 RNQMCD GS AHT21 PCB?

It measures 22.9 × 20.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the REV0.0.1 RNQMCD GS AHT21 use?

21 parts, built around the AHT21, 1.0T-4P卧贴, 0402B104K160CT and LDK105CBJ106MVLF. 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 REV0.0.1 RNQMCD GS AHT21 KiCad files?

From the GroundStudio/GroundStudio_AHT21_module repository on GitHub, at the commit this page was made from: the board is Hardware/REV0.0.1 - Kicad6/REV0.0.1 RNQMCD_GS AHT21.kicad_pcb and its schematic Hardware/REV0.0.1 - Kicad6/REV0.0.1 RNQMCD_GS AHT21.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the REV0.0.1 RNQMCD GS AHT21 design in my own project?

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