About the ESP32 Board

ESP32 Board is an open source ESP32 PCB design by danilocoletto, published on GitHub under the CC0-1.0 license. It is a 2-layer board measuring 82 × 65 mm, with 6 components from 5 distinct parts.

Its main chip is the ESP32 - DEVKIT, from the ESP32 family. By type, the board carries 2 ICs and 1 connector.

It belongs with the iot & wireless and test & measurement designs in this gallery.

From the project

- Real-time embedded architecture using ESP32 + FreeRTOS - 24-bit precision ADC (ADS1255) for nanoampere current measurements - 16-bit DAC waveform generation for electrochemical techniques - Modular analog front-end (AFE) design - Designed for voltammetry and amperometry - KiCad

- Real-time embedded architecture using ESP32 + FreeRTOS - 24-bit precision ADC (ADS1255) for nanoampere current measurements - 16-bit DAC waveform generation for electrochemical techniques - Modular analog front-end (AFE) design - Designed for voltammetry and amperometry - KiCad open hardware design - Firmware based on ESP-IDF

This repository contains the open-source hardware and firmware for a Real-Time Embedded Potentiostat. Designed as a high-precision modular extension board, this instrument allows for advanced electrochemical analysis (Voltammetry, Amperometry) in field applications.

ESP32 Board: common questions

What microcontroller does the ESP32 Board use?

The ESP32 Board is built around the ESP32 - DEVKIT, from the ESP32 family.

How big is the ESP32 Board?

The ESP32 Board measures 82 × 65 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32 Board?

6 components, from 5 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 ESP32 Board design files?

From the danilocoletto/ESP32-Based-Embedded-Potentiostat-Extension-Board 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 ESP32 Board design in my own project?

Yes, under the terms of its CC0-1.0 license, which danilocoletto chose for the repository.

Can I test firmware for the ESP32 Board 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.
