## Overview

A desk nameplate PCB that spells **PAUL** in 36 white 0402 LEDs, powered by a USB-C connector. Plug in any iPhone charger and the name lights up.

## Design

- **Font:** 3x5 pixel dot-matrix, 3 mm pitch, 4 mm letter gap
- **LEDs:** 36 white 0402 (P=8, A=10, U=11, L=7)
- **Current limiting:** 36x 220 ohm 0402 resistors (~14 mA per LED)
- **Power:** USB-C (TYPE-C-31-M-12) with 5.1k CC pulldowns for default 5V
- **Board:** 64x24 mm, 2-layer, rounded edges
- **Total draw:** ~504 mA (within USB-C default 900 mA budget)

## Circuit

All LEDs wired in parallel: VBUS -> 220 ohm resistor -> LED anode, cathode -> GND. A 100 nF bypass cap smooths the VBUS rail. Two 5.1k resistors on CC1/CC2 tell the USB-C host to supply 5V.

Built with tscircuit + adom-tsci.
