About the Yatchy PCB

Yatchy is an open source ESP32 PCB design by Szybet, published on GitHub. It is a 4-layer board measuring 33.8 × 38 mm, with 89 components from 37 distinct parts.

Its main chip is the ESP32-C6-MINI-1-N4, from the ESP32 family. Other key parts include the MCP23018-E/MJ, MCP73831T-2ATI/OT and TLV75533PDBV. By type, the board carries 27 connectors, 22 capacitors, 19 resistors, 5 diodes, 4 ICs and 3 transistors.

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

A modular, hackable, improved watchy like watch

Don't scream "IT'S NOT OPEN SOURCE", let me explain myself.

- First, this work is not a watchy fork, it's a complete redesign obviously inspired by the watchy form factor, but nothing more. - I don't want SQFMI to steal this design and sell it. Not even if I could profit of it. His bad software, bad communication, sometimes bad and questionable hardware decisions have killed so much potential of the watchy. - I don't want someone to just make money off it and give nothing back to…

Yatchy: common questions

What microcontroller does the Yatchy use?

The Yatchy is built around the ESP32-C6-MINI-1-N4, from the ESP32 family.

How big is the Yatchy PCB?

The Yatchy measures 33.8 × 38 mm, has 4 copper layers and is 1 mm thick.

How many components are on the Yatchy?

89 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the Yatchy design files?

From the Szybet/Yatchy repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Yatchy design in my own project?

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

Can I test firmware for the Yatchy 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.
