SilentSignal - Haptic Communication for Sports

Prototype Manufacturing Plan

A practical path from the current Arduino reference build to smaller wearable prototype units that can be assembled, tested, and field-tried.

Prototype target

Small PCBA + separate wearable enclosure

1. Miniaturize the Electronics

Turn the breadboard/Arduino concept into a small custom PCB or carrier board.

Use the existing Arduino + 433MHz concept as the reference design, then make a smaller board around the core subsystems.

MCU

pre-certified RF module

haptic motor driver

battery, charging, and protection

buttons and switches

antenna

programming pads

2. Have a PCBA Shop Build the Boards

Send the fabrication and assembly package to a shop that can build small runs.

US-based PCB assembly, quoting, sourcing, tracking, and prototype-to-production continuity.

US quick-turn prototyping and small/mid-volume PCB assembly.

Lower-cost overseas prototype PCB assembly, PCB fabrication, and mechanical services.

Overseas PCB fabrication, assembly, and mechanical services for prototype builds.

Maker-friendly PCB, PCBA, and related prototyping services.

3. Have Enclosures Made Separately

For 5-50 units, use 3D printing or CNC instead of injection molding.

3D printing, CNC, sheet metal, and later low-volume molding.

On-demand prototype and production parts.

Prototype-to-production mechanical parts and manufacturing support.

3D printed or CNC enclosures when one vendor for boards plus plastic is useful.

4. Do Final Assembly / Box Build

Bring the finished electronics and enclosure together into testable units.

Box build means turning the assembled board into a complete wearable prototype.
