About this Gig
Turning an audio product idea into working hardware? I design circuit boards for smart, connected audio devices Bluetooth speakers, soundbars, portable amplifiers, and voice-enabled audio gadgets. Every board is built around clean power delivery, low-noise audio paths, and reliable wireless performance, so your device sounds as good as it looks.
What I offer:
- Bluetooth speaker and soundbar PCB design
- Portable and desktop amplifier circuit design (Class D, Class AB)
- Voice-assistant/smart audio device hardware (mic array, wake-word ready circuits)
- MCU-driven audio control (ESP32, STM32 WiFi/BLE audio streaming and app control)
- Battery-powered audio device design (charging circuit, power management)
- Multi-driver/multi-channel speaker circuit design
- Volume control, EQ, and input switching circuits
- Fritzing prototyping diagrams for early-stage visualization
- Production-ready schematic capture and PCB layout (Altium, KiCad, or Eagle)
- Component selection and BOM optimization
- Gerber files, DFM checks, and prototype-ready outputs
Send me your product concept, target features, or existing schematics, and let's build audio hardware people actually want to use.
