I need a gyroscope for balancing my robot. After a long search and high prices i found this:

input voltage 5v. Uses the same 3 pin configuration of ez board. Should be perfect,

Is it compatible?


Also can i ask you what could it be the best hardware to measure the speed of the robot? I hope mine will reach >60 mph so i'll need something to keep track of it
