Questions
How big is the ESP32S3 A7672S PCB?
It measures 65.8 × 100.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32S3 A7672S use?
110 parts, built around the LM2596S-5.0, AMS1117-3.3, TXB0108RGY and USBLC6-2SC6. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ESP32S3 A7672S KiCad files?
From the Vtechcode/ESP32S3_A7672S repository on GitHub, at the commit this page was made from: the board is ESP32S3-A7672S/ESP32S3-A7672S.kicad_pcb and its schematic ESP32S3-A7672S/A7672S.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32S3 A7672S design in my own project?
Its repository states no licence, so its author keeps all rights: ask Vtechcode before reusing the design.

Pyramid of brightness

This was supposed to be a pyramid (or more of a triagle) but I thought I'd be too difficult to arrange the pixels in a neat way. So I made it a square. The name stuck.
