Got the 4 axis Nema23 Kit from Longs Motor. Came with the above as the interface. Question how do I power it up? Can I connect it to the 36V PSU? It draws only 5V and am concerned about it blowing the board. Am also confused by the pin out as the board is not very clear on that front and how to hook it up the the DM542 Stepper Drivers. Any advice is appreciated. Thanks.
