This is a fancy upgrade to standard 16x2 LCDs, instead of just having
blue and white, or red and black, this LCD has full color RGB characters
on a dark/black background! That means you can change the character
display colors to anything you want - red, green, blue, pink, white,
purple yellow, teal, salmon, chartreuse. This LCD looks strikingly good
in person
We had these custom made to our specification so that you can
use them in existing LCD projects and they'll still work - just that
only the red LED will be used (so it will appear red-on-black). The
extra two pins (17 and 18) are for the green and blue LEDs. The LCD has
resistors on board already so that you can drive it with 5V logic and
the current draw will be ~20mA per LED. There's a single LED backlight
for the entire display, the image above showing 3 colors at once is a
composite!
Comes with a single 16x2 RGB backlight LCD, 10K necessary contrast potentiometer and strip of header.
