  "readme": "## Overview\n\nA warm-white LED desk nameplate that spells **TAMARA** in a 3x5 bitmap pixel font. Designed as an Adom molecule (92 x 38 mm, 4-pin machine contact) so it can be manufactured on the InstaPCB workcell.\n\n## How it works\n\n- **54 warm-white LEDs** (0603) arranged in 6 letters: T-A-M-A-R-A\n- Each LED has its own **390 ohm current-limiting resistor** (0402)\n- All LED+resistor pairs wired in **parallel** from VBUS to GND\n- **USB-C connector** on the south edge with 5.1k ohm CC pull-downs\n- **10uF bulk cap** for inrush smoothing\n- Total draw: ~275mA at 5V (1.4W) -- any phone charger handles it\n\n## How to use it\n\n1. Grab any USB-C cable (iPhone charger works)\n2. Plug one end into the board's south edge\n3. Plug the other end into a 5V USB-C power source\n4. TAMARA lights up warm white\n\n## Bill of Materials\n\n| Component | Value | Package | Qty |\n|-----------|-------|---------|-----|\n| LED | warm-white | 0603 | 54 |\n| R | 390 ohm 1% | 0402 | 54 |\n| R_CC1, R_CC2 | 5.1k ohm | 0402 | 2 |\n| C_BULK | 10uF X5R | 0805 | 1 |\n| J1 | TYPE-C-31-M-12 | USB-C | 1 |\n\n## Design details\n\n- Board: 92 x 38 mm, 2-layer, 1.6mm FR4\n- Pixel pitch: 3mm LED-to-LED\n- Letter gap: 3mm between letters\n- Warm-white Vf = 3.0V, so 390 ohm at 5V gives ~5mA per LED\n- Back side has full documentation silkscreen (how to power, BOM, maintenance)\n\n## Built with\n\nAuthored in tscircuit (TSX), previewed with adom-tsci, exported to KiCad.\n",
