About the Palm scan PCB

Palm scan is an open source PCB design by coolvnod, published on GitHub. It is a board, with 6 components from 5 distinct parts.

By type, the board carries 4 resistors, 1 connector and 1 diode.

It belongs with the sensors designs in this gallery.

From the project

Open palm-vein scanning: ESP32-S3 + NIR sensor hardware, firmware, and an own CNN recognition model. Door release as the first demo.

Nets are global labels — the same name on any page is the same wire. Pages are defined in PAGES; a box that does not fit its page fails loudly.

Edit PARTS in the generator and the table in ../../docs/NETLIST.md — the checker exists precisely so the two can't drift apart silently.

Fine — but then stop running the generator, it will overwrite your edits. Move the wires around, keep the net names.

6 components, 5 distinct parts.
