About the Time o matic PCB

Time o matic is an open source ESP32 PCB design by Hasnat4763, published on GitHub under the MIT license. It is a 2-layer board measuring 60.8 × 74.1 mm, with 23 components from 19 distinct parts.

Its main chip is the ESP32-WROOM-E, from the ESP32 family. Other key parts include the MP1584EN-LF-P and CH340C. By type, the board carries 10 resistors, 6 capacitors, 3 ICs, 2 connectors, 1 diode and 1 inductor.

It belongs with the usb & debug tools designs in this gallery.

From the project

This is a pc statistics displayer which uses USB to transmit RTSS data over serial.

I made this because during gameplay it is pretty disorienting while MSI afterburner is giving an overlay and I dont have any display on my casing to do the same work.

Time o matic: common questions

What microcontroller does the Time o matic use?

The Time o matic is built around the ESP32-WROOM-E, from the ESP32 family.

How big is the Time o matic PCB?

The Time o matic measures 60.8 × 74.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Time o matic?

23 components, from 19 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 Time o matic design files?

From the Hasnat4763/time-o-matic 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 Time o matic design in my own project?

Yes, under the terms of its MIT license, which Hasnat4763 chose for the repository.

Can I test firmware for the Time o matic 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.
