Questions

How big is the Pcb test PCB?

It measures 90 × 90 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Pcb test use?

11 parts, built around the VS1053B-L and MAX98306. 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 Pcb test KiCad files?

From the IsuruPabasara/TheConductor repository on GitHub, at the commit this page was made from: the board is PCB Design/pcb_test.kicad_pcb and its schematic PCB Design/pcb_test.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Pcb test design in my own project?

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