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 Input board PCB?

It measures 90.8 × 43.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Input board use?

9 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 Input board KiCad files?

From the increpare/PuzzleScript-labs repository on GitHub, at the commit this page was made from: the board is hardware/devkit/waveshare_43_input/input_board.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 Input board 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).
