I will design bluetooth audio pcb speaker amplifier and wireless audio electronics

Are you looking to build a commercial Bluetooth speaker, a high-fidelity amplifier, or a custom wireless audio product? I am an electronics hardware engineer specializing in low-noise, high-performance audio electronics. I will take your concept from a napkin sketch to a production-ready PCB layout. What I can design for you:

Bluetooth Audio Receivers & Transmitters (Qualcomm, ESP32, BES, Nordic chipsets)

High-Efficiency Class-D, Class-AB, or Headphone Amplifiers (TI, Infineon, STM)

Digital Signal Processing (DSP) integration for speaker tuning and EQ

Power Management Units (PMU) for battery-powered portable speakers (Li-ion/LiPo charging)

Smart Speakers, Wireless Audio Arrays, and TWS Earbud circuitry

My Design Focus:

1. Strict Noise Mitigation: Isolation of digital/RF switching noise from sensitive analog audio paths to ensure zero hiss, hum, or buzzing.

2. Signal Integrity: Optimized impedance matching for Bluetooth/RF traces and heavy copper pour considerations for thermal and ground loops.

3. Production-Ready Output: Full manufacturing files provided according to your manufacturers  design rules.
