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. Our tutorials and diagrams will have you up and running in no time! For more information, check out our detailed step-by-step tutorial for both Arduino & CircuitPython
The controller will be a HD44780-compatible, see the HD44780 datasheet with the detailed commands for control
