Modifications

Motors are controlled TB6612 MOSFET driver: '''with 1.2A per channel current capability''' (20ms long bursts of 3A peak), a big improvement over L293D drivers and there are built-in flyback diodes as well.

We even had a little space so we added a polarity protection FET on the power pins and a bit of prototyping area. And the HAT is assembled and tested here at Adafruit so all you have to do is solder on the included 2x20 plain header and the terminal blocks.
