About the Esp32-sensor daq PCB

Esp32-sensor daq is an open source ESP32 PCB design by EldinLz, published on GitHub. It is a 2-layer board measuring 73.5 × 65.5 mm, with 16 components from 10 distinct parts.

Its main chip is the ESP32-C3-DevKitM-1, from the ESP32 family. Other key parts include the MCP6002-xP. By type, the board carries 6 test points, 5 resistors, 2 ICs, 1 connector, 1 diode and 1 capacitor.

It belongs with the sensors and dev boards & breakouts designs in this gallery.

From the project

Custom ESP32-C3 sensor data acquisition PCB, firmware, fabrication files, and validation plan.

A custom two-layer PCB and Arduino firmware project for collecting ambient-light, temperature, humidity, and pressure data with an ESP32-C3.

This project combines a custom KiCad carrier board with an ESP32-C3 DevKitM-1. A photoresistor signal is conditioned by an MCP6002 op-amp and sampled by the ESP32 ADC, while a BME280 breakout provides environmental data over I2C. Six labeled test points expose the primary power and signal nets for structured bring-up and debugging.

Esp32-sensor daq: common questions

What microcontroller does the Esp32-sensor daq use?

The Esp32-sensor daq is built around the ESP32-C3-DevKitM-1, from the ESP32 family.

How big is the Esp32-sensor daq PCB?

The Esp32-sensor daq measures 73.5 × 65.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32-sensor daq?

16 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32-sensor daq design files?

From the EldinLz/esp32-sensor-daq repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Esp32-sensor daq design in my own project?

The repository has no license, so all rights stay with EldinLz. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Esp32-sensor daq 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.
