I will design bluetooth speaker amplifier audio pcb wireless audio electronics smart sp

If you're building a Bluetooth speaker, a portable audio device, or a smart speaker product, I design the full board around that Bluetooth audio circuits, amplifier PCB, power section, and the wireless side, all working together instead of bolted together.

Portable and smart audio products have a few things that need to be right at the same time: the amplifier needs to be efficient and quiet, the power section needs to handle battery charging and regulation cleanly, and the wireless audio path (Bluetooth, I2S, codec) needs to not introduce noise into the amp stage. I lay the board out with all three in mind, keeping the noisy digital and wireless sections separated from the analog amplifier path.

Whether you already have a schematic or just know what the product needs to do (Bluetooth in, speaker out, battery powered), tell me where you're starting from. You'll get a schematic (if built from scratch), PCB layout, Gerbers, and a BOM ready for fabrication and assembly.

Inbox me your specs power source, speaker impedance/wattage, and Bluetooth chip preference if you have one and I'll confirm scope and pricing.
