    I have purchased an EVShield and an NXTShield but have so little information about the electronics.  For example, what is the drive capability of the motor ports or how much power can the 5V supply.  Would it be possible for mindsensors to share the schematics, so I can look up the regulators/motor driver ICs?  Has anyone else extracted the schematics yet?

    Sorry, I cannot release the full product schematics. The NXShield uses the LB1836ML chip and the EVShield uses the DV8833PWR chip to drive the motors. 
    Both devices use the LD1117S50CTR 5V regulator.

    How about a block diagram then? Or am I just not looking in the right places?

    Hi....i think it is not possible for them to share the schematics and all because it is a matter of copyright of the product. Also it is the matter of product related security. And also in the above comment they shared enough data for you, from there you can go for your problem troubleshooting or solution finding. And if you are looking for a block diagram then try to find out the system lock diagram that you can easily find. Also one more way is there that try to trace out the system given i.e boards and connected componenets etc.
