Questions
How big is the Aqproto PCB?
It measures 25.5 × 62.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Aqproto use?
31 parts, built around the ESP32-S3-MINI-1-N8, ENS210, SGP41-D-R4 and D3V3XA4B10LP. 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 Aqproto KiCad files?
From the HOUXA8/aqproto repository on GitHub, at the commit this page was made from: the board is aqproto.kicad_pcb and its schematic aqproto.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Aqproto design in my own project?
Its repository states no licence, so its author keeps all rights: ask HOUXA8 before reusing the design.
