so I went off and designed a whole cyberdeck pcb, it’s kinda sick, it's a full-on deck with ports, buttons, blinky stuff, and that clean hacker aesthetic. built it because laptops are boring and carrying around raw PCBs just hits different.the board’s got space for a pi, a couple usb ports, an oled, and some clicky switches. stuff’s laid out in a way that makes sense, but also makes you look like you’re about to jack into the matrix at a coffee shop. the idea is simple cram as much functional coolness as possible onto one board and still make it portable enough to flex at meetups. this whole thing started with a sketch on a sticky note and now it’s a real life project(obviously i need money to make it real). i even left space for expansion headers because future proofing or whatever. no idea how many late nights went into routing this lol

Questions
How big is the MainPCB PCB?
It measures 161 × 87 mm and has 4 copper layers, 1.2 mm thick.
What parts does the MainPCB use?
194 parts, built around the ESP32-S2FH4, FE1.1S-BSOP28BCN, W25Q128JVSIQ and AT24CM01-SSHM-B. 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 MainPCB KiCad files?
From the rohit-env/minideck-pcb repository on GitHub, at the commit this page was made from: the board is pcb/mainPCB.kicad_pcb and its schematic pcb/displayPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MainPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask rohit-env before reusing the design.
