README
README.mdPCB Desk Display
The idea was to have a special purpose, small footprint PCB for connecting an I²C Display, Button and Status LED.
The PCB
The PCB including the ESP32-C3 Antenna has a total footprint of 20mmx30mm. The files can be found in ./pcb.
The Code
The code currently is only a small placeholder to test the different parts of the PCB. The files can be found in ./code in form of a PlatformIO project.

Questions
How big is the Desk display PCB?
It measures 20 × 24 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Desk display use?
16 parts, built around the ESP32-C3-WROOM-02-H4, AMS1117-3.3 and WS2812B. 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 Desk display KiCad files?
From the oltdaniel/PCB_deskDisplay repository on GitHub, at the commit this page was made from: the board is pcb/desk_display.kicad_pcb and its schematic pcb/desk_display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Desk display design in my own project?
Its repository states no licence, so its author keeps all rights: ask oltdaniel before reusing the design.
