pcb routing
schematic
designing is done. next step is getting the board manufactured, recieving it , adding the code and testing it and seeing if everything works!!
The entire pcb was designed in easyeda but duet to the repo submision checks error i have added the .kicad_pcb file but please refer to only the files in the folder named psycon-wearable.

Questions
How big is the Psycon wearable PCB?
It measures 61.5 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Psycon wearable use?
47 parts, built around the CH340C, ESP32-WROOM-32D-H4, ADS1115QDGSRQ1 and MAX30102EFD+T. 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 Psycon wearable KiCad files?
From the CodeSakshamY/Half-life-HackClub repository on GitHub, at the commit this page was made from: the board is Psycon-wearable.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Psycon wearable design in my own project?
Its repository states no licence, so its author keeps all rights: ask CodeSakshamY before reusing the design.
