- Autofocus camera module with 2592×2592px JPEG capture
- 240×240px 1.4" LCD with a consistent 15–20 fps live preview

- Hot swappable battery
- Screen dims automatically when idle to save power
- TPU protective sleeve and lanyard design also available to print
Everything you need is in the GitHub repo:
- Bill of Materials - parts list with cost estimates
- Build Guide (PDF) - full step by step assembly
- Print ready Bambu Studio files - sliced for transparent PETG and PETG-CF
- Individual STLs - if you prefer to slice yourself
- CAD file (.STEP) - for modifications and remixes
- Software + installer - camera app with installation guide and controls reference
In addition, I made the build guide and the BOM available on this hackaday project page for quick browsing.
