About the Tamagotchi PCB

Tamagotchi is an open source ESP32 PCB design by TaniWanKenobi, published on GitHub. It is a 2-layer board measuring 56.8 × 66.3 mm, with 7 components from 5 distinct parts.

Its main chip is the XIAO-ESP32-C6, from the ESP32 family. Other key parts include the HS96L03W2C03. By type, the board carries 3 switches, 2 ICs and 1 battery holder.

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

From the project

A custom PCB-based Tamagotchi virtual pet built with the XIAO-ESP32-C6 microcontroller, featuring a 0.96" OLED display, three buttons, and a buzzer.

I made the project to have my own completely customizable tamagatchi! I also want you to customize yours however you want - check my tutorial for instructions!

To use this, simply flash the xiao with the firmware in the repo! Here is an assembly diagram:

Tamagotchi: common questions

What microcontroller does the Tamagotchi use?

The Tamagotchi is built around the XIAO-ESP32-C6, from the ESP32 family.

How big is the Tamagotchi PCB?

The Tamagotchi measures 56.8 × 66.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tamagotchi?

7 components, from 5 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 Tamagotchi design files?

From the TaniWanKenobi/tamagotchi 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 Tamagotchi design in my own project?

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

Can I test firmware for the Tamagotchi 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.
