Issue:
The latest revision (3.3.0) of the GoPiGo3 controller board has significant differences from the 3.2 version boards, especially in the critical areas of the level-shifting interface.
This is the revision 3.3 controller board
And this is the revision 3.2 controller.
You will note that in the top-center of the revision 3.3 board there is a network of MOSFETS and diode-resistor isolators replacing the level-shifter IC on the lower, (revision 3.2), PCB.
This is a significant change, and there may be others that I haven't noticed yet.
Request:
Please post a current schematic for the revision 3.3 series controller boards.
