The Sun Harvester Driver Boards can be wired to the Sun Harvester circuit using two different methods. If you need to control multiple machines, then you will wire the driver boards using the Sun Harvester Shield Breakout Boards.
If you only need to control one machine, then you can simply solder the connections directly to the Sun Harvester Shield.
Wiring the Driver Boards to the Sun Harvester Shield Breakout Boards
A Sun Harvester Driver Board can be connected to a Sun Harvester Shield Breakout Board simply by using an ethernet cable and two wires.
Warning!: Make sure you are using a “straight through” ethernet cable. This is the more common type of ethernet cable. If you use a “crossover” ethernet cable, the circuit won’t work. Here is a link to an outside website that describes how to tell the difference between the two types. http://www.petri.co.il/csc_the_basics_of_ethernet_cabling.htm
Also make sure that the wires you use to make the GND and M+ Connections are as big or bigger than the wires coming from the power supply (not pictured below). Basically, if you use the thin wire similar to what is found in other parts of the circuit you could melt it!
The image below shows how to wire the Sun Harvester Driver Board to the Breakout Board.
To add more driver boards, simply connect them in the same manner as above filling the empty connectors from left to right. Each breakout board supports up to four driver boards.

If needed, more breakout boards can be added when the first is filled up. This is explained more in depth on the Connecting Breakout Boards to Sun Harvester Shield V1.0 page.
Wiring the Driver Board Directly to the Sun Harvester Shield V1.0
If you only need to control one machine, then you do not need a breakout board in the circuit. You can simply wire the driver board directly to the shield.
The image below shows how to do it. For the most part, you are just matching the labeled connections on the driver board to the labeled connections on the shield.
Note that the Enable connection on the shield is left unused here as are the ENABLE, GND, and VCC connections on the right side of the driver board. Also 5V on the shield goes to VCC to clear up any possible confusion.
