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. |
|
|
OK the control port header is done. Check your solder joints visually and continue onto the next steps |
Solder Driver Headers for LEDs
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. |
|
|
OK now you have the control and LED pads with headers. Check your solder joints visually and continue onto the next steps |
|
|
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 |
