I will design ai companion pin pcb, voice interfaces, sensors and wireless hardware

An AI companion pin needs a carefully planned combination of voice input, audio output, wireless communication, processing, and battery power in a very small wearable device. I will help you develop the electronics architecture for a voice-first assistant, wearable recorder, connected badge, or hands free AI hardware prototype.

Possible design features include:

Microphone and speaker interfaces

MCU, processor, or AI module integration

BLE and Wi-Fi connectivity using suitable components

Buttons, status LEDs, and additional sensor interfaces

Battery charging, protection, and power regulation

Compact PCB layout, schematic, BOM, and manufacturing files according to scope

I will review your use case, dimensions, selected components, audio requirements, and expected operating time before proposing the design. This makes it easier to identify hardware limitations early and choose a practical architecture instead of forcing components into an unsuitable layout.

You can bring an existing schematic or start with a clear product concept. I will help translate your requirements into a structured electronics design for prototyping.
