For no reason in particular, is there any extensive documentation available for the V5 brain and its hardware?
There is this https://www.vexrobotics.com/v5-architecture.html for documentation on the parts as well as some of the code.
As well as this https://api.vexcode.cloud/v5/html/ for v5 text documentation.
Not sure if this is what you are looking for but I hope it helps.
Then click “Product Specs”
Additional information can be seen when clicking “Learn more”
Edit//: @sinful beat me with much of the information, props xD
