Precision BLE Wearable Device Development

Job ID: 39336190

Budget: $250 – $750 USD

Compact BLE Wearable – Full Stack Hardware & Firmware Development
We’re developing a compact BLE input wearable with:
- Flex PCB
- Capacitive touch interface (supporting gestures/combos)
- Pogo pin charging

All components must fit within ~1 mm internal thickness.

Technical Overview:
- Internal Surface Area: ~900 mm² total
- 600 mm² for touchpad and routing only
- 300 mm² for ICs and components
- Battery Area: ~300 mm² for an ultra-thin curved Li-Po battery.
BLE SoC: Nordic (e.g., nRF52810) or Dialog (e.g., DA14531)
Touch Controller: Cypress CY8CMBR3116 or similar
Power: Battery-powered, BLE HID, with PC-side GATT configuration.

Focus Areas:
High-Precision Touch Control – Smooth, accurate input via gestures and combos.
Ultra-Compact Integration – Reliable implementation within a tight 1 mm internal thickness.
Energy Efficiency – Maximize usage time with a small battery; very low power design required.
Mechanical Fit – Must align with the provided industrial design (ID) structure and dimensional constraints.
PC-Side Configuration – Support for gesture combo macros and touch sensitivity adjustment via a BLE-connected desktop tool.

Scope:
-Schematic design
- Compact flex PCB layout
- Firmware: BLE HID, touch gesture processing
- Power optimization strategies
- Bring-up and testing support

This is a focused design — few components, but requires precision, space-conscious engineering, and battery efficiency.

If you’re experienced with compact BLE wearables and CapSense integration, we’d love to hear from you. More technical details available under NDA if needed.
