About the Mainboard Layout No daisy chain PCB

Mainboard Layout No daisy chain is an open source ESP32 PCB design by ReadHeadRedemption, published on GitHub. It is a 2-layer board measuring 207 × 174.8 mm, with 87 components from 38 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the CP2102-GM and PCA9534PW,118. By type, the board carries 32 connectors, 24 resistors, 13 capacitors, 6 switches, 4 ICs and 4 diodes.

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

Mainboard Layout No daisy chain: common questions

What microcontroller does the Mainboard Layout No daisy chain use?

The Mainboard Layout No daisy chain is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Mainboard Layout No daisy chain PCB?

The Mainboard Layout No daisy chain measures 207 × 174.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mainboard Layout No daisy chain?

87 components, from 38 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Mainboard Layout No daisy chain design files?

From the ReadHeadRedemption/SeniorDesignSp26Su26 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Mainboard Layout No daisy chain design in my own project?
