ESP32 Wearable PCB & Enclosure

Job ID: 39815662

Budget: €750 – €1,500 EUR

I am building a small wearable that revolves around an ESP32-S3 and now need the complete hardware package designed—from the board itself to a snug, ready-to-print enclosure.

PCB requirements
The board must host the ESP32-S3 plus power-management circuitry with 3,7V Lipo-Battery, an audio input/output stage, a compact speaker, LED ring, and a single capacitive touch sensor button. I have moderate freedom on overall footprint, yet the layout should stay mindful of wearable ergonomics and battery placement.

Enclosure
Alongside the electronics I need a 3D model for the housing that keeps the components secure, offers good acoustic ventilation for the speaker, and exposes the touch button and LED ring elegantly. A physical on/off switch. Heart-Shaped rounded kid-friendly design and materials.
STL/STEP files ready for FDM or SLA printing are ideal.

Deliverables
• Schematic and PCB layout (KiCad, Altium, or equivalent)
• Clean Gerber/ODB++ files, drill files, and fabrication notes
• Complete BOM with manufacturer part numbers
• 3D board model for fit checks
• Printable enclosure files and simple assembly guide

Acceptance
Design files must open without errors, pass standard DRC/ERC checks, and fit together in a single print without post-processing other than light sanding.

If you have experience squeezing rich feature sets onto compact wearables with ESP32, I’d love to see how you would approach this project.
