Compute Module 4 Hub

Has anyone designed a hub that will work with the compute module 4? I am new to this community and currently we only use the NovaStar control system but would like to work on a cost-effective solution using the CM4. Example hub attached that is designed around the A5s receiving card.



Example shown is with Hub 73 but Hub 75 would be fine and more useful to this community. I could have them designed for us but for testing purposes it would be great to use one that already exists!

I think you’re in the wrong forum, we use the Teensy and ESP32, not the RPi

What is this board supposed to plug into?
Does it use ethernet or those long white looking connectors for data?
