Tamagotchi PCB Design and Firmware Project

An open-source Tamagotchi, built on an ESP32 with an ST7735 LCD and physical buttons. A digital pet resembling me responds to feeding, playing, and dressing up. Stats are persistent (saved to EEPROM)

PCBWay sponsors 3D Printing and PCB assembly costs on this project during the prototyping phase! If you are interested in their awesome fabrication services please check them out. They offer 3D prototyping, PCB design, and assembly, as well as CNC metal fabrication. Costs are reasonable and the quality is as good as it gets. Thank you, PCBWay, for sponsoring me!

ESP32Pet: common questions

What microcontroller does the ESP32Pet use?

The ESP32Pet is built around the ESP32-DEVKIT-V1, from the ESP32 family.

How big is the ESP32Pet PCB?

The ESP32Pet measures 82.3 × 79 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32Pet?

11 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32Pet design files?

From the dishishshawn/ESP32Pet repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP32Pet design in my own project?

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

Can I test firmware for the ESP32Pet 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.
