Note : Tinkercad doesn't allow to add a key switch in the schema so it's replaced by a slide switch.

Modelisation of the PCB
Testing
V1
After soldering the components, here are the problems encountered:
- the pin holes of the components had an edge too thin,
- the writing for the arduino pin holes should be in the back,
- the space between the key switch holes was incorrect,
- the pin holes for the battery and the lighter where to close (this may cause unwanted bad contact),
- they were no drill holes for screwing in the keyboard,
- it was hard to tell the difference between the ground and 5V on each components.
Here are a few ideas for improvement :
- add a battery holder in the back of the PCB,
- add some holes in the corners of the PCB to be able to screw it,
- add resistor values to make soldering easier,
- make the 5V pin holes squared.
V2
All the problems with the V1 where fixed in this version (V2).

Questions
How big is the 7355608 v2 PCB?
It measures 100 × 159.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 7355608 v2 use?
14 parts. 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 7355608 v2 KiCad files?
From the umyedi/7355608 repository on GitHub, at the commit this page was made from: the board is model/V2/7355608_v2.kicad_pcb and its schematic model/V1/7355608_v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 7355608 v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask umyedi before reusing the design.
