This is a fancy upgrade to standard 20×4 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
One nice thing about these LCDs is that they are an elegant upgrade, but 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 ~40mA per LED (there are two LEDs, 20mA each). 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 20×4 RGB backlight LCD, 10K necessary contrast potentiometer and strip of header. Our tutorials and diagrams will have you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
