About the Mainboard layout V1 PCB

Mainboard layout V1 is an open source ESP32 PCB design by ReadHeadRedemption, published on GitHub. It is a 2-layer board measuring 172 × 152.9 mm, with 64 components from 28 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the PCA9534PW. By type, the board carries 32 connectors, 19 resistors, 5 capacitors, 3 ICs, 2 transistors and 2 switches.

From the project

The master schematic is within "Senior design mainboard32826 backup"

This was the version that everything was verified in as of 4/10/2026

Then for the sake of layout, and neatness broken out into their own project files for each discrete board. This includes swapping and non-swapping

Mainbourd layout pre-weeks check 1 has most up to date version of mainboard PCB this will eventually be made neater again as development continues but this is noted to avoid mistakes for now
