I have the Motor Shield v1.2 from RadioShack. I’m looking for a schematic of it.
I found the v1.0 schematic on the wiki at seeedstudio.com/wiki/Motor_Shield_V1.0 . However, my board seems slightly different; the schematic shows SENSE A and SENSE B headers for adding current sensing resistors, presumably to measure the two main motors. I can’t seem to find these headers on my board.
Specifically I would like to check if there is some way to access the AREF pin on this board.
Are there design files for the Motor Shield v1.2 available anywhere?
