So I'm a total novice at electronics and am on a steep learning curve so bear with me :-) I'm using EZ-Robot to control my B9 and have a question about H-Bridges. EZ recommends the L298N. I've reviewed the tutorial (see below) and think I grasp the process. What I'm unclear on is how much power the board can take. In the video the power source used is only battery. My system is 12 volts. Is that within the specs and how many H Bridges could I route through a single board?
