techmannih/usbc-charger

This code defines a detailed electronic hardware design for an 85-265VAC to USB-C PD 18W wall charger, including the schematic layout and physical component placements such as connectors, filtering inductors, capacitors, resistors, protection diodes, and an isolated power module, all integrated with 3D models and mechanical enclosures.

# Footprints

Use a footprinter string for standard packages.

For JLCPCB parts, run `tsci import <C-number>`. It uses a string only when there is a close footprinter string match. Otherwise it keeps the exact EasyEDA footprint. `--use-exact-footprint` skips conversion.

```

Syntax: `<family>[pin-count]_<modifier><value>...`. Include units.

Use custom `<footprint>` TSX only for unsupported manufacturer geometry, such as asymmetric pads, slots, shield tabs, segmented thermal pads, or mixed SMT and through-hole layouts. Never guess.
