Parts
The PCB consists of a 4-Layer stack. All required parts are through hole components with the exception of the capacitor C1 which is a combined footprint. Besides the PCB itself you need the following parts:
- 24 Led WS2812B Ring with 4 contacts (diameter 66mm)
- SMD Capacitor 5mm diameter, about 10uF
- (alternative) THT Capacitor, about 10uF
- Wemos D1 mini ESP32 (ESP8266 will not work)
- PN532 RFID Reader V3 (red modules, sold under elechouse brand or clones)
- mini pushbutton (the tiny black/silver ones)
- (optional) 14 Pin Male and 13 Pin Female 2.54mm Pin Header/Socket for expansion port

Questions
What parts does the 2logDot use?
8 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 2logDot KiCad files?
From the 2log-io/2log-dot-hardware repository on GitHub, at the commit this page was made from: the board is 2logDot.kicad_pcb and its schematic 2logDot.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 2logDot design in my own project?
Its repository states no licence, so its author keeps all rights: ask 2log-io before reusing the design.
