Assembly

Assemble the IS31 Driver Board

We'll start by soldering in the 7-pin 'control' header. Break the headers you received so that you have a 7-pin piece and follow these steps.

	Prepare the header strip: Cut the strip to length if necessary. It will be easier to solder if you insert it into a breadboard - long pins down
	Add the breakout board: Place the breakout board over the pins so that the short pins poke through the breakout pads
	And Solder! Be sure to solder all pins for reliable electrical contact. (For tips on soldering, be sure to check out our Guide to Excellent Soldering).
	OK the control port header is done. Check your solder joints visually and continue onto the next steps

The two side strips are what are used to control the charlie-plexed LEDs

	Prepare the header strip: Cut the strip to length if necessary. It will be easier to solder if you insert it into a breadboard - long pins down
	Add the breakout board face up: Place the breakout board over the pins so that the short pins poke through the breakout pads
	And Solder! Be sure to solder all pins for reliable electrical contact. (For tips on soldering, be sure to check out our Guide to Excellent Soldering).
	OK now you have the control and LED pads with headers. Check your solder joints visually and continue onto the next steps

Now we'll sandwich on the charlieplexed LED panel

	The LEDs face out and connect to the two side header strips. The panel is symmetric - you can flip it around either way and it will work fine
	Solder in the two long header strips. Not all are connected on the LED matrix but it makes the connections mechanically stable.
	Check your solder joints visually and continue onto the next steps
	Now you can trim the long header with diagonal cutters. Cut one or two pins at a time Watch out for flying header bits. Wear eye protection and be careful!
	Cut both sides down for the best look
	You're done! Check your solder joints visually and continue onto the next steps
