KiCad-LED-Key

# LED Key PCB (KiCad)

A simple LED Key PCB designed in KiCad. The board uses a through-hole LED, a single through-hole current-limiting resistor, and a momentary switch footprint. Connection pads are clearly labeled, and the overall layout is clean and easy to assemble.

## Features
- Through-hole LED and resistor  
- Momentary switch footprint  
- Clean, minimal KiCad layout  
- Straightforward power and signal pads

## How It Works
The LED is powered through a single current-limiting resistor, and the momentary switch provides the primary input. External power, ground, and signal lines connect through the labeled pads.
