Questions

How big is the Panel PCB?

It measures 61 × 99 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Panel use?

168 parts, built around the TPS62842DGRR, ZD25WQ16CTIGT, DW01A and SRV05-4. 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 Panel KiCad files?

From the simonyiszk/sem18-pcb repository on GitHub, at the commit this page was made from: the board is hw/panel.kicad_pcb and its schematic hw/mcu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Panel design in my own project?

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