About this Gig
Need a custom smart speaker PCB with reliable Bluetooth audio, battery management, and embedded firmware?
I design smart speaker electronics and custom PCBs for portable and connected audio products, from schematic and component selection through PCB layout, power management, and firmware integration.
I can design:
- Smart speaker & Bluetooth speaker PCBs
- Bluetooth audio and wireless connectivity
- MCU, audio codec, amplifier and microphone interfaces
- Li-ion/Li-Po battery charging and power management
- USB, I2C, SPI, UART and I2S interfaces
- Embedded firmware and hardware integration
- Prototype and production-ready electronics
Deliverables:
- Complete schematic
- PCB layout
- BOM and component selection
- Embedded firmware
- Gerber & manufacturing files
- Source design files and documentation
I focus on clean hardware architecture, reliable audio performance, efficient power management, and production-ready PCB design tailored to your speaker's requirements.
Send your speaker specifications, enclosure constraints, preferred components, and any existing reference designs to get started.

FAQ
Can you design around my existing speaker enclosure?
Yes. I can work with your enclosure dimensions, speaker size, mounting points, and component height restrictions.
Can you select the right components for my speaker?
Yes. I can recommend the MCU, Bluetooth solution, audio codec, amplifier, battery, charger, and power components based on your requirements.
Can you optimize the design for battery life?
Yes. I can optimize power architecture, charging, sleep modes, and component selection for efficient battery operation.
Can you integrate microphones or voice-control hardware?
Yes. I can integrate microphone inputs, audio processing interfaces, and related peripherals for smart-speaker applications.
Can you work with an existing or unfinished PCB design?
Yes. I can review, troubleshoot, modify, or complete an existing schematic or PCB design.
