About the Esp32-giant chronometer PCB

Esp32-giant chronometer is an open source ESP32 PCB design by becem0, published on GitHub under the MIT license. It is a 2-layer board measuring 131 × 90 mm, with 32 components from 11 distinct parts.

Its main chip is the ESP32-DevKitC, from the ESP32 family. Other key parts include the ULN2803A and 74HC595. By type, the board carries 13 ICs, 8 connectors, 8 capacitors, 1 diode and 1 resistor.

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

From the project

?? Giant 6-digit 7-segment race chronometer powered by ESP32, 24V COB LED strips, custom KiCad 10 PCB, and SIM800L GSM telemetry.

An end-to-end industrial-grade embedded system featuring a 6-digit giant 7-segment display driven by high-lumen 24V COB LED strips, a custom modular KiCad 10 PCB, an ESP32-WROVER-E dual-core controller hosting an asynchronous real-time Web dashboard, and SIM800L GSM cellular telemetry.

Designed, developed, and fabricated by Bacem AMEUR (National Engineering School of Monastir - ENIM) during an engineering internship at Chrono Sports Events.

Esp32-giant chronometer: common questions

What microcontroller does the Esp32-giant chronometer use?

The Esp32-giant chronometer is built around the ESP32-DevKitC, from the ESP32 family.

How big is the Esp32-giant chronometer PCB?

The Esp32-giant chronometer measures 131 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32-giant chronometer?

32 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32-giant chronometer design files?

From the becem0/esp32-giant-chronometer 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-giant chronometer design in my own project?

Yes, under the terms of its MIT license, which becem0 chose for the repository.

Can I test firmware for the Esp32-giant chronometer 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.
