About the ProtoBoard PCB

ProtoBoard is an open source ESP32 PCB design by ciborg971, published on GitHub under the MIT license. It is a 4-layer board measuring 56 × 48 mm, with 84 components from 28 distinct parts.

Its main chip is the ESP32-S3-MINI-1, from the ESP32 family. Other key parts include the CD74HC4067SM, LM1084-5.0, HY2120, WS2812-2020 and LM1084-3.3. By type, the board carries 31 resistors, 24 capacitors, 14 ICs, 11 connectors, 2 transistors and 2 switches.

It belongs with the power & battery and iot & wireless designs in this gallery.

From the project

A small PCB for great (next gen) gloves

A small board (48 x 56 mm) for great gloves !

Still a work in progress, current version does NOT work

This design does NOT work right now, do NOT buy it unless you can debug it by yourself You can buy the board via PCBWay using the file ProtoBoard.kicad_pcb.zip and the BOM ProtoBoard.xlsx.

This project is sponsored by PCBWay, thanks to them for their quality PCB + assembly !

ProtoBoard: common questions

What microcontroller does the ProtoBoard use?

The ProtoBoard is built around the ESP32-S3-MINI-1, from the ESP32 family.

How big is the ProtoBoard PCB?

The ProtoBoard measures 56 × 48 mm, has 4 copper layers and is 4.69 mm thick.

How many components are on the ProtoBoard?

84 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the ProtoBoard design files?

From the ciborg971/ProtoBoard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ProtoBoard design in my own project?

Yes, under the terms of its MIT license, which ciborg971 chose for the repository.

Can I test firmware for the ProtoBoard 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.
