I will design bluetooth audio pcb speaker amplifier and wireless audio

Are you developing a commercial Bluetooth speaker, a portable wireless audio device, or an IoT sound system? Generic hardware designers often misroute sensitive audio traces, causing annoying background hum, buzzing, and poor wireless range.

I provide professional Bluetooth audio PCB design, speaker amplifier layouts, and wireless audio electronics engineering engineered for crisp, noise-free sound reproduction.

From compact, battery-powered Bluetooth amplifier boards to complex IoT stream devices, I ensure clean power distribution and optimal signal path isolation between digital microcontrollers and analog audio stages.

What I Specialise In:

• Wireless MCUs: ESP32 Bluetooth audio, ESP32-S3, BLE modules, and CSR/Qualcomm audio chips.
• Digital Audio Paths: I2S audio routing, high-resolution DAC/ADC integration, and audio codecs.
• Amplification & Power: Class-D amplifier circuits (TI, Maxim, ESS), battery charging (BMS), and low-noise regulators.
• Form Factors: Portable speakers, custom wireless audio receivers, and wearable acoustic devices.

What Deliverables You Receive:

• Production-ready Gerber RS-274X or X2 files
• Exhaustive Bill of Materials (BOM) with LCSC/Mouser part numbers
• Centroi
