About the Jay-Tab PCB

Jay-Tab is an open source ESP32 PCB design by Jay-Tai, published on GitHub under the MIT license. It is a 2-layer board measuring 109.3 × 90.7 mm, with 12 components from 10 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N16R8, from the ESP32 family. Other key parts include the AMS1117-3.3. By type, the board carries 4 resistors, 3 connectors, 2 ICs and 2 capacitors.

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

From the project

The Jay-Tab is a project that features an e-ink display that has features, such as intergrating Google Calendar, Google Home, and a timer, along with a home tab!

I made this project mainly out of personal interest. As to get the money to make this project in real life, I used Hack club's stardance program!

There are many features that are packed into Jay-Tab:

- Beautifully 3D-Printed case! - 2-Layer PCB enclosing all the hardware! - Running on the ESP32-S3 WROOM - 7.5" E-Ink touchscreen display to hold all the features of the Jay-Tab! - Home screen that shows all you need to know at a glimpse - Calendar screen that shows all the events happening in your day! - Timer screen that has a timer that you can play a timer on a dedicated screen on your…

Jay-Tab: common questions

What microcontroller does the Jay-Tab use?

The Jay-Tab is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the Jay-Tab PCB?

The Jay-Tab measures 109.3 × 90.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Jay-Tab?

12 components, from 10 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 Jay-Tab design files?

From the Jay-Tai/Jay-Tab 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 Jay-Tab design in my own project?

Yes, under the terms of its MIT license, which Jay-Tai chose for the repository.

Can I test firmware for the Jay-Tab 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.
