ESP32 PCB is an open-source printed circuit board by buttonbugs, from the buttonbugs/Stuffed-Crust repository on GitHub, published under the MIT licence. It is a 2-layer board of 24.3 × 25.5 mm with 39 parts on 73 nets, routed with 274 tracks and 62 vias.
It is built around the ESP32-S3-MINI-1U-N8, AP2112K-3.3 and H3LIS331DL, with the TPS54302, SMAJ36A and BAT54CW among its other parts. Its parts include 12 capacitors, 12 resistors, 5 diodes, 5 connectors and 4 ICs. It belongs with the robots and motor control boards and the ESP32 boards of this library.
This repository contains the code for Wildcat Robotics' team Stuffed Crust. This is a fork of the open source melty brain code, openmelt 1, with improved translational drift algorithm, adapted watchdog 2 for Teensy 4.0 and some other changes specific to Stuffed Crust's design.

It measures 24.3 × 25.5 mm and has 2 copper layers, 1.6 mm thick.
39 parts, built around the ESP32-S3-MINI-1U-N8, AP2112K-3.3, H3LIS331DL and TPS54302. 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.
From the buttonbugs/Stuffed-Crust repository on GitHub, at the commit this page was made from: the board is ESP32_PCB/ESP32_PCB.kicad_pcb and its schematic ESP32_PCB/ESP32_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
