This is version 2.0 of the previously successful kickstarter project I launched last year. I have a ton of these PCB boards left over and it got me thinking. Why not find a P channel MOSFET with the same pinout and use it to control the direction of the motor also.
I looked around and found the IRF5210. I ordered up a batch and tested them out. All thats left to do now is order a large quantity for the price break and assemble the rest of the boards.
