Pinout different than previous backpacks? #2

Hey Nate, I am working on the testbed for these right now. I noticed that the pinout for the connections to the LCD are slightly different than our previous backpacks. There are two extra pins (GRN and BLU).

Where on the LCD are these two pins intended to be connected?

The two extra pins and the solder jumpers allow the backpack to be used on LCDs that have an RGB backlight. On regular single color backlit LCDs you just don't connect them.

Yep. That makes sense. Sorry, I could have probably figured that out by looking at the schematic a little longer.

I didn't know we had screens with RGB backlights.They look cool!
