Wiring the Displays

If you have not already done so, refer back to this tutorial to wire up the first of the displays as shown below.
Each of the displays comes with both data and power connectors. Use the data connectors to bridge from the connector labelled OUTPUT on the first display to INPUT of the next display. If you have three displays then also bridge the data to the final display.
Attach the power connectors for all the displays to the displays and then use male to male jumper wires as shown above to connect all the red +5V connectors together and all the black negative connections together. Note that as long as you are connecting red-wired terminals on the power leads to other red-wired connections and black connections to the other black connections, it does not matter which of the connections on the four pin power connectors you use.

Finally use male to male jumper wires on the final display to connect it to the screw terminals of the 2.1mm to Screw Jack Adapter.

The power supply must be 5V at 4A (mostly text) or 10A (all pixels used, bright graphics). DO NOT USE A POWER SUPPLY OF MORE THAN 5V.
