TECHNICAL SPECIFICATIONS | CUSTOM ESP32-S3 R2 ASTROMECH | BUILDER DOCUMENTATION
Wee2-D2 is a custom-built, active-duty astromech droid built in 2025 for use with the Badlands Droid Builders and the 501st Legion's Badlands Garrison. This repository is the public builder documentation — schematics, BOM, hardware manuals, wiring, and operator guides. The droid's firmware lives in a separate repository.
The chassis is built from the acclaimed 3D files by Mr. Baddeley.
The documentation in this repo is rendered live at:
https://ruzzler.github.io/Wee2-D2/
That is the intended way to read these docs — the sidebar, schematic, image lightbox, and search-friendly URLs work there. Reading the raw Markdown on GitHub also works but skips the rendering.

Companion projects (separate repositories):
- Firmware — ESPHome firmware that runs on the droid. Currently private; will be published when ready for community distribution.
- Web App (PWA) — Web Bluetooth control panel.
- Android APK — Capacitor wrap of the web app for at-venue use.
Each link is a high-density manual with pinouts and wiring.
