PCB MainBoard
About the PCB MainBoard
PCB MainBoard is an open source ESP32 PCB design by Oberson-Antoine, published on GitHub. It is a 2-layer board measuring 75.8 × 60.4 mm, with 10 components from 9 distinct parts.
Its main chip is the ADAFRUIT-ESP32-S3, from the ESP32 family. Other key parts include the S09-EY9-DC-DC, BOB-12009 and INA260. By type, the board carries 4 ICs, 4 connectors and 2 resistors.

PCB MainBoard: common questions
What microcontroller does the PCB MainBoard use?
The PCB MainBoard is built around the ADAFRUIT-ESP32-S3, from the ESP32 family.
How big is the PCB MainBoard?
The PCB MainBoard measures 75.8 × 60.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the PCB MainBoard?
10 components, from 9 distinct parts. The full bill of materials is listed on this page.
Where can I download the PCB MainBoard design files?
From the Oberson-Antoine/Trotten-Electric-Table repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the PCB MainBoard design in my own project?
The repository has no license, so all rights stay with Oberson-Antoine. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the PCB MainBoard without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
