Overview
Moonboard is an open-source printed circuit board by Stanlee1234, from the Stanlee1234/Moonboard repository on GitHub. It is a 2-layer board of 99.5 × 70.5 mm with 17 parts on 32 nets, routed with 119 tracks and 13 vias.
It is built around the DHT11. Its parts include 6 diodes, 6 switches, 2 ICs, 1 resistor and 1 connector. It belongs with the ESP32 and RISC-V boards of this library.

Moonboard is a Tamagotchi-style game played on a custom PCB. The idea is simple: look after your moon every day and help it move through its eight phases. I wanted it to feel like a small object you could keep on your desk, pick up, and play with for a minute.
I made this project for Hack Club Half Life.
Try it without the board
I currently don't have the physical board, so no demos. I do have a firmware simulator. To get there,
open Firmware/simulator/index.html and you can try out most features of my console!
Use Q / W / E for the top row and A / S / D for the bottom row, or just
click the buttons. The simulator is intentionally simple, but it makes it much
easier to try ideas without constantly flashing the board.
What it can do
- Show all eight moon phases on the OLED
- Let you move around with a six-key matrix
- Use the rotary potentiometer for game input
- React to tilting and shaking through the MPU6050
- Read temperature and humidity from the DHT11
- Run on a XIAO ESP32-C3, with fallbacks for testing without every sensor connected

Questions
How big is the Moonboard PCB?
It measures 99.5 × 70.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Moonboard use?
17 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 Moonboard KiCad files?
From the Stanlee1234/Moonboard repository on GitHub, at the commit this page was made from: the board is KiCAD/moonboard.kicad_pcb and its schematic KiCAD/moonboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Moonboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Stanlee1234 before reusing the design.
