Overview
Starbie is an open-source printed circuit board by SharKingStudios, from the SharKingStudios/Starbie repository on GitHub, published under the MIT licence. It is a 2-layer board of 96.6 × 82.8 mm with 11 parts on 25 nets, routed with 32 tracks and 0 vias.
It is built around the DHT11. Its parts include 2 ICs, 2 connectors, 2 switches and 1 resistor. It belongs with the ESP32 and RISC-V boards of this library.
Main components

README.mdStarbie
Starbie is a tiny motion-controlled digital pet: basically a desktop Tamagotchi with minimal gameplay buttons. Instead of pressing controls, you interact with it by physically moving the board.
Looking for the guide! You can find it here!
What it is
Starbie is designed to sit on your desk, show its personality on a small display, and react to how you handle it. Tilting, moving, and otherwise checking in on your pet are meant to be part of the experience.
The board includes a microcontroller, display, motion sensor, and environmental sensor in a compact PCB design. It is USB powered and built around beginner-friendly through-hole soldering for the add-on components.
Why?
This project was created to be the week 1 beginner tutorial for halflife!
Project status
The PCB design, renders, and an Arduino starter firmware are included here. The default program is a two-eye pet with a tilt-controlled radial menu, hidden stats, and a shake reaction.
Software
Firmware/ contains one self-contained Arduino IDE sketch for the XIAO ESP32-C3. Builders customize pins, menu actions, starting values, and motion settings together at the top of the sketch. The folder also includes a draggable browser simulator. See the firmware README for setup notes.

Questions
How big is the Starbie PCB?
It measures 96.6 × 82.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Starbie use?
11 parts, built around the DHT11. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Starbie KiCad files?
From the SharKingStudios/Starbie repository on GitHub, at the commit this page was made from: the board is PCB/Starbie.kicad_pcb and its schematic PCB/Starbie.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Starbie design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
