This is rev 1.0 of the mini Controller. I patched the 3.3V on the back-side so this is feeded 3.3V from DRV10983 and Works fine between 8-28V IN. I also added 1000uF capacitors that I hope will be sufficient to absorb sparks. I have not added the MAX3485 yet, but I can test without this.
This shows the Controller + motor Connected. The vero Board in the midle is so I can measure phases on a Scope. Time to Write some test code.
Reading the datasheet I should be able to Control the DRV10983 simply by sending a pulse between 1KHz to 25KHz. The duty cycle is the speed. But, I also have I2C Connected for the more Advanced Interface.
