Portenta X8, Speaker, Microphone and Battery Integration

Hi there. We're a start-up on a mission to make smart glasses software (Text to Speech). Right now, we're working to develop prototype for testing purposes with something called Portenta X8, and we want to add a microphone, camera, Battery and a USB Type-C camera to it. Our goal? Create smart glasses that run smoothly on a battery for at least 4-5 hours.

Project Objectives:

1. Microphone and Speaker Integration:
Identify and recommend suitable microphone and Speaker compatible with the Portenta X8.
Provide detailed instructions on connecting the microphone to the Portenta X8,

2. Battery Selection and Integration:
Identify a high-performance battery solution capable of providing a minimum of 4-5 hours of continuous operation.
Provide step-by-step instructions on connecting and integrating the selected battery with the Portenta X8.
3. Camera Integration (USB Type-C):
We are using Camera which has USB Type C port. It would be great to connect it without directly connecting to USB port. (For instance cutting the end and connecting wires directly to pins to save the space)

We urgently need to solve this three and I am looking forward for someone who can help
cheers, David
