About this Gig
Smart Sonic Toothbrush PCB Engineering
Is your sonic toothbrush prototype struggling with limited space, unstable power, charging issues, or unreliable BLE?
I turn your concept into a compact, manufacturable electronics system built around real product constraints not just a schematic.
What I Deliver:
- Sonic PCB Architecture
- Miniature PCB Layout
- BLE Connectivity
- Battery Management
- Charging Circuitry
- Motor Control
- Battery Indicator
- Sensor Integration
- Waterproof Considerations
- DFM Optimization
- BOM Preparation
- Gerber Generation
Why Choose Me?
- Space conscious engineering
- Power efficient architecture
- Manufacturing ready files
- Clean component selection
- Mechanical aware PCB planning
- Prototype to production thinking
I solve the hidden problems that can cause overheating, poor battery life, charging failures, EMI issues, assembly problems, and enclosure conflicts before they become expensive revisions.
MESSAGE ME BEFORE ORDERING with your toothbrush concept, requirements, or existing files. Let's build the electronics around your product not force your product around the PCB.

FAQ
Will the PCB survive a real toothbrush environment?
I consider water exposure, vibration, compact assembly, connector reliability, and manufacturing constraints during development. The goal is not simply a working schematic, it is a PCB prepared for a demanding consumer product.
What happens if the brush head, motor, or battery changes later?
I structure the electronics with practical interfaces and component considerations, making future revisions easier instead of forcing you to rebuild the entire PCB from scratch.
Can the Bluetooth connection work reliably in such a small device?
Yes. The BLE architecture, antenna placement, grounding, power integrity, and component positioning are considered early to avoid designing a board that works only on the bench.
Will the PCB actually fit inside a compact toothbrush body?
Yes. I account for miniature PCB constraints, component height, brush-head clearance, battery placement, and enclosure space so the electronics are planned around the real product not an oversized prototype.
How will you prevent battery or charging problems?
I consider the Li-ion/LiPo power path, charging circuit, protection, regulation, battery indication, and current demands to reduce overheating, unstable charging, and unexpected shutdowns.
