Found a guide in Chinese for the EP.
I can't read Chinese, but it shows how to connect to the Microbit, arduino, PI and Jetson Nano boards.
This thing would make the ultimate Jetbot.
Please release it soon!

Is this what you're looking for? Can't remember where I found it, but I think its the same document: https://robomaster-dev.readthedocs.io/en/latest/

There is also a english version of the same documentation although it is not as complete.

Also, what do you mean by "release it"? The EP is already available although buying it is non-trivial (and it is kinda expensive).
