BLE Wearable PCB & Firmware
Budget: $250 – $750 USD
I am at the concept stage of a no-screen wearable: a 35 × 27 × 5 mm board that speaks BLE to a companion mobile app once every minute. The first milestone is a rock-solid schematic, PCB layout, and production-ready embedded code; performance, reliability, and clean power budgeting matter more than cosmetic polish right now.
What I need you to build
• A complete schematic and compact multi-layer PCB (Gerber + stack-up) that meets the size above, integrates a low-power BLE SoC, battery charger/monitor, and all passives.
• Firmware that advertises, connects, and pushes an update every 60 s while meeting aggressive sleep-current targets.
• Integrated power-management strategy, including component selection, dynamic power states, and battery-life projection.
• One functional prototype and a concise test report validating wireless range, current draw in each mode, and successful 1-minute data transfers.
Timeline
I would like the prototype tested and documented within roughly one month, so efficient communication and fast iteration are essential. Being located in Malaysia—or able to ship prototypes here quickly—will simplify logistics.
How to stand out
Show experience with ultra-small wearables, low-power RF design, Nordic/Dialog/TI BLE stacks, and any past work where you squeezed days of runtime from tiny batteries. That practical background will carry more weight than lengthy proposals.
Deliverables for project close
• Schematic (PDF + source)
• Manufacturing files (Gerber, drill, BoM, pick-and-place)
• Firmware source and build instructions
• Test results with measured current charts and BLE performance notes
• Brief design documentation for future revisions
If you can hit those marks, let’s talk and start cutting copper.
