DFR0767 - Is there a schematic available?

Is there a schematic available for the DFR0767???

Here is the product information:

Raspberry Pi Compute Module 4 IoT Router Carrier Board Mini - DFRobot

https://www.dfrobot.com/product-2242.html 

I was able to find a schematic for another base board, but the size is too large.

Thank you for the help!
