About the Metrodisplay PCB

Metrodisplay is an open source ESP32 PCB design by vuktacic, published on GitHub under the MIT license. It is a 2-layer board measuring 99.2 × 52.8 mm, with 53 components from 13 distinct parts.

Its main chip is the ESP32-DEVKITC, from the ESP32 family. Other key parts include the SN74AHCT245PWR. By type, the board carries 22 capacitors, 15 connectors, 12 resistors, 3 ICs and 1 diode.

It belongs with the displays & leds designs in this gallery.

Metrodisplay: common questions

What microcontroller does the Metrodisplay use?

The Metrodisplay is built around the ESP32-DEVKITC, from the ESP32 family.

How big is the Metrodisplay PCB?

The Metrodisplay measures 99.2 × 52.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Metrodisplay?

53 components, from 13 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 Metrodisplay design files?

From the vuktacic/metrodisplay 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 Metrodisplay design in my own project?

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

Can I test firmware for the Metrodisplay 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.
