MVP Design
Project Overview
The goal is to create a USB-C hub that can connect to a laptop and provide 3 to 5 Individual HDMI outputs (identify as individual displays, not clon display), with at least one output supporting audio. This device will leverage DisplayPort Alt Mode over USB-C and will be compatible across multiple operating systems.

Key Components
USB-C Connector: A USB-C port to connect to the laptop.
Display Controller IC: A chip that can handle multiple HDMI outputs. Options include:
DisplayLink: A popular choice for multi-display setups, compatible with most operating systems.
MST Hub (Multi-Stream Transport): For DisplayPort Alt Mode, which allows multiple displays to be daisy-chained.
HDMI Outputs: 3 to 5 HDMI ports to connect to external displays.
Audio Support: Ensure at least one HDMI output supports audio.
Power Supply: External Power Supply (may consider support for 1 to 2 displays under USB-C input, but this will surely require external power input)
Enclosure: A durable casing to house the components ideally aluminum alloy to support high temperatures generated by components and favor cooling
Cooling Solutions: If necessary, to prevent overheating during extended use.

Design Considerations
Compatibility: Ensure that the device works seamlessly with Linux, Windows, and macOS. This may involve using drivers for DisplayLink or ensuring that MST is supported.
Resolution Support: Support for various resolutions (e. G., 1080P, 4K) depending on the capabilities of the HDMI outputs and the Display Controller IC.
Power Delivery: Ensure that the device can handle power delivery to charge the laptop while using external displays.
Driver Support: Research and potentially collaborate with DisplayLink for driver support across different operating systems.
User Interface: Consider adding LED indicators to show power status and connection status for the displays.
Form Factor: Design a compact and portable device that is easy to carry and use.
Implementation Steps
Research and Development:

Investigate available Display Controller ICs and their compatibility with HDMI and USB-C.
Review existing multi-display adapters to identify features and shortcomings.
Circuit Design:

Create schematics for the USB-C connection, power management, and HDMI outputs.
Design the PCB layout to accommodate all components.
Prototype Development:

Fabricate a prototype PCB and assemble the components.
Test the functionality of the device with different laptops and operating systems.
Software Development:

If using DisplayLink, work on integrating and testing the necessary drivers for each operating system.
Ensure that the device is recognized and functions correctly across all platforms.
Testing and Validation:

Conduct extensive testing to ensure compatibility with various laptops, OS versions, and display configurations.
Test audio output functionality and resolution support.
Enclosure Design:

Design an ergonomic and aesthetically pleasing enclosure for the device.
Consider materials that provide durability and heat dissipation.
Certification and Compliance:

Ensure that the device meets relevant compliance standards (e. G., CE, FCC) for electronics.
Test for electromagnetic interference (EMI) and ensure safe operation.
Production and Marketing:

Develop a production plan for manufacturing the device at scale.
Create marketing materials and a website to promote the product.
