Designs PCB schematics and layouts for VanDaemon hardware projects, primarily the ESP32-based 8-channel LED dimmer. KiCad 7+ uses S-expression format for all files. The project follows automotive-grade design practices for reliability in vehicle environments.

| Concept | Format | Example |

| Comments | # prefix only | # Power section |
| Component reference | (property "Reference" "R1") | Resistor R1 |
| Pin connection | (wire (pts ...)) | Net connection |
| Symbol instance | (symbol (lib_id "...") | Component placement |
| Net label | (label "VCC" ...) | Named net |
KiCad does NOT support semicolon comments. Use # for comments in KiCad files.
# GOOD - Hash comments work
# Power regulation section
; BAD - Semicolons are NOT comments, they become part of the data
