About the NeOClock PCB

NeOClock is an open source ESP32 PCB design by fthiebolt, published on GitHub. It is a 2-layer board measuring 200 × 80 mm, with 43 components from 21 distinct parts.

Its main chip is the ESP32_dev_30p, from the ESP32 family. Other key parts include the DCDC_LM2596, AMS1117, SA15-11GWA and SAA1064. By type, the board carries 11 resistors, 8 ICs, 8 diodes, 5 connectors, 5 capacitors and 3 switches.

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

From the project

neOCampus Arduino | home of the neOSensors end-devices

This repository provides support for the following neOCampus boards: neOSensor boards based on ESP32 neOSensor-AirQuality board (ESP32) from CNRS' LCC lab. * neOSensor boards based on ESP8266 (rev. >= V2)

All this work was undertaken at Université Toulouse 3 / IRIT laboratory in the context of the neOCampus operation.

We added support to our neOCampus IoT management infrastructure named sensOCampus to enable a central configuration for all of our neOSensor boards; these boards will then be able to publish their data to our infrastructure and to have those data stored in our databases.

NeOClock: common questions

What microcontroller does the NeOClock use?

The NeOClock is built around the ESP32_dev_30p, from the ESP32 family.

How big is the NeOClock PCB?

The NeOClock measures 200 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the NeOClock?

43 components, from 21 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 NeOClock design files?

From the fthiebolt/neOCampus-arduino repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the NeOClock design in my own project?

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

Can I test firmware for the NeOClock 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.
