About this Gig
Are you looking to develop a small wearable audio device prototype with professional electronics design and low-power performance? I specialize in designing compact, efficient, and production-ready wearable audio hardware from concept to prototype.
I will help you build devices such as smart earbuds, wearable recorders, voice assistants, or custom audio wearables using modern embedded systems and optimized audio architectures.
What I can design:
- MEMS microphone & microphone preamplifier circuits
- Audio codec IC, DSP processing & Class-D amplifier integration
- Miniature speaker (micro speaker) systems
- Low-power MCU solutions (ESP32, STM32, ARM Cortex-M series)
- I2S audio interfaces with RTOS-based firmware architecture
- Bluetooth Low Energy (BLE), Bluetooth & Wi-Fi connectivity
- NFC pairing, RF matching & PCB antenna design
- Li-Po / coin cell battery power management & protection circuits
- Sensor integration (proximity, PPG heart-rate, wearable features)
Deliverables may include:
Schematics, PCB layout, BOM, firmware architecture, and prototype-ready files.
Lets turn your wearable audio idea into a real working prototype message me before ordering to discuss your project!
