Ever since https://hackaday.io/project/18648-nokia-3310-5110-display-board I've wanted to slap on an ESP module and some buttons to make a nice little portable handheld. Now with some googling and checking out other projects how they get their stuff done and a bit time on hand while on vacation I'm using every spare minute to work on this PCB. There are some minor things I'm not sure about that need testing, but the general concept is clear.
The last version - R 3.2.3 - seems to got lost, it was rebranded to Game Toy and some pinouts were changed to make more sense.

Questions
How big is the LAMEBOY PCB?
It measures 45.7 × 67.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LAMEBOY use?
71 parts, built around the PCF8574T, MCP73831, BC847S and TPS2113PWG4. 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 LAMEBOY KiCad files?
From the davedarko/LAMEBOY repository on GitHub, at the commit this page was made from: the board is Schematics/REV3.2.3/kicad/LAMEBOY.kicad_pcb and its schematic Schematics/Kicad_current/LAMEBOY/LAMEBOY.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LAMEBOY design in my own project?
Its repository states no licence, so its author keeps all rights: ask davedarko before reusing the design.
