README
README.mdGizmoCard is my business card.
It is also a gadget that runs Python:
- fully programmable;
- with Wi-Fi and BLE support;
- an USB port to plug it into a computer and do things with it;
- and a catchy matrix display for good measure.

Questions
How big is the Gizmo card PCB?
It measures 85.6 × 53.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Gizmo card use?
147 parts, built around the ESP32-C3FN4, W25Q128JVSIQ, H7233-1 and PRTR5V0U2X. 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 Gizmo card KiCad files?
From the neta79/gizmo_card repository on GitHub, at the commit this page was made from: the board is hardware/project/gizmo_card.kicad_pcb and its schematic hardware/project/gizmo_card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gizmo card design in my own project?
Its repository states no licence, so its author keeps all rights: ask neta79 before reusing the design.
