Questions

How big is the Soily PCB?

It measures 25 × 129.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Soily use?

54 parts, built around the 625L3C040M00000, AP2112K-3.3, ESP32-H2-MINI-1U and USBLC6-2SC6. 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 Soily KiCad files?

From the danstiner/embedded repository on GitHub, at the commit this page was made from: the board is HW/Soily.kicad_pcb and its schematic HW/BL54L15μ_DevKit/BL54L15μ_DevKit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Soily design in my own project?

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