Questions

How big is the Baby present PCB?

It measures 53.8 × 132.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Baby present use?

44 parts, built around the ATMEGA328P-AU, LM2623LD and CR2032. 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 Baby present KiCad files?

From the TimGoll/pcb_baby_present repository on GitHub, at the commit this page was made from: the board is byb_present/baby_present.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Baby present design in my own project?

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