I will design bluetooth audio speaker amplifier pcb

Building a Bluetooth speaker, wireless audio receiver or portable audio device? I design the schematic and PCB layout so your board is clean, quiet and ready to manufacture.

WHAT YOU GET

- Schematic and 2-layer PCB layout for a Bluetooth audio board with up to 40 components

- Bluetooth module or ESP32, audio codec or DAC, and speaker amplifier integration, following the datasheets

- I2S audio routing, with grounding and power filtering planned to keep digital noise out of the audio path

- Gerber, drill and BOM files for JLCPCB, PCBWay or any fab

- Editable source files (KiCad, Altium or EasyEDA)

WHY WORK WITH ME

- I design ESP32 and wireless boards and rework existing ones regularly, so I catch layout mistakes that cause noise, hum or respins

- Clear communication and on-time delivery

PLEASE SEND ME

Your module or chip, amplifier or codec choice (or your goals), power source (battery or USB), speaker details, board size, and any enclosure limits.

Battery charging and protection, 4-layer boards, reviews of existing boards and larger designs are available through Extras. I deliver design files only. I do not provide sound-quality guarantees, Bluetooth certification,
