README

PuzzleScript Card — hardware

Custom PCB for the PuzzleScript Card handheld.

You don't draw schematics — we generate them

bash

node hardware/card/schematic/generate_kicad.js
# or: make handheld_card_kicad

Then install KiCad 8 once and open hardware/card/card.kicad_pro. See OPEN.md for step-by-step.

Generated	What it is
`card.kicad_pro` / `card.kicad_sch`	Full hierarchical project (9 sheets)
`schematic/sheets/*.kicad_sch`	Power, compute, display, controls, …
`card.kicad_pcb`	Board outline + keep-outs + placed fit/preview footprints with ratsnest pads
`schematic/connectivity.json`	Net source of truth (edit this, then regenerate)

bash

node hardware/card/schematic/connectivity_test.js
node hardware/card/schematic/generate_kicad_test.js
make handheld_pcb_export          # if make available

Questions

How big is the Pocket card controller PCB?

It measures 80.5 × 37 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Pocket card controller use?

17 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 Pocket card controller KiCad files?

From the increpare/PuzzleScript-labs repository on GitHub, at the commit this page was made from: the board is hardware/pocket_card/electronics/pocket_card_controller.kicad_pcb and its schematic hardware/card/card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Pocket card controller design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
