A KiCad PCB design created for ETEC 3300. The board is built around the ESP32-S2FN4R2 and combines USB-C connectivity, 2.4 GHz Wi-Fi (via an on-board chip antenna), a battery charging circuit, an LDO power rail, an audio amplifier, an LCD interface, RGB status LEDs, and a multi-button probe input — all in a single compact design.

All symbols and footprints are in libs/PartsLibrary3300.kicad_sym and libs/PartsLibrary3300.pretty/. Both are linked via ${KIPRJMOD} in sym-lib-table and the project footprint library table, so they resolve automatically when the project is opened in KiCad regardless of where it is cloned.
Footprints originate from the KiCad standard library, SnapEDA, and manufacturer-published CAD data (Johanson Technology, Walsin, Molex, GCT). Attribution is noted in the footprint description fields within the library files themselves.
