10W Portable Bluetooth Speaker – PCB Design & Development

About the project

I am looking for an experienced PCB designer/electronics engineer to design a compact PCB for a 10W portable Bluetooth speaker. The goal is to develop a reliable, compact and production-ready PCB that can be used for a small commercial Bluetooth speaker product. Required Features * Bluetooth audio connectivity * 10W Class-D audio amplifier * 4Ω speaker output * Single-cell Li-ion battery operation * Battery charging and protection circuit * USB Type-C charging input * Power ON/OFF control * Play/Pause button * Previous/Next track control * Volume Up/Down control * LED status indication * Battery protection * Low-battery indication * Proper audio filtering and noise reduction * Compact PCB suitable for a portable speaker enclosure PCB Requirements * Compact PCB layout with optimized component placement * 2-layer PCB preferred, unless a different layer count is technically required * Proper grounding and power routing * Good audio PCB layout practices * Protection against short circuit, over-current and over-voltage where applicable * Components should be readily available and suitable for production * Design should consider low BOM cost and easy assembly Preferred Components The designer can recommend suitable ICs/components based on performance and cost. Possible areas include: * Bluetooth audio module/SoC * Class-D amplifier IC * Li-ion charging IC * Battery protection/BMS IC * Voltage regulation/power management * Buttons and LEDs * USB Type-C connector Deliverables I expect the following final files: 1. Complete circuit schematic 2. PCB layout 3. Gerber files 4. BOM with manufacturer part numbers 5. Pick-and-place/Centroid file 6. PCB fabrication files 7. Complete KiCad/Altium source files 8. PCB 3D model/rendering 9. Assembly/component placement drawing 10. Design documentation and basic testing recommendations
