LCDs & Displays / Character

LCD backpacks reduce the number of pins needed to connect to an LCD. LCDs are a fun and easy way to have your microcontroller project talk back to you. Character LCDs are common, and easy to get, available in tons of colors and sizes. We've written tutorials on using character LCDs with an Arduino (or similar microcontroller) but find that the number of pins necessary to control the LCD can be restrictive, especially with ambitious projects....

Standard HD44780 LCDs are useful for creating standalone projects. 16 characters wide, 2 rowsWhite text on blue backgroundConnection port is 0.1" pitch, single row for easy breadboarding and wiringPins are documented on the back of the LCD to assist in wiring it upSingle LED backlight included can be dimmed easily with a resistor or PWM and uses much less power than LCD with EL (electroluminescent) backlightsCan be fully controlled with...

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...

Standard HD44780 LCDs are useful for creating standalone projects. 20 characters wide, 4 rowsWhite text on blue backgroundConnection port is 0.1" pitch, single row for easy breadboarding and wiringSingle LED backlight with a resistor included, you can power it directly from 5V. If it's too bright for you, it can be dimmed easily with a resistor or PWM and uses much less power than LCD with EL (electroluminescent) backlightsCan be fully...

Adding a character display to your project or computer has never been easier with the new Adafruit USB or TTL serial backpack! This custom-designed PCB can connect to the back of any 16x2 or 20x4 character LCD and does everything you could want: printing text, automatic scrolling, setting the backlight, adjusting contrast, making custom characters, turning on and off the cursor, etc. It can even handle our RGB backlight LCDs with full 8-bit PWM...

Standard HD44780 LCDs are useful for creating standalone projects.  This product is similar to our Standard LCD 16x2 display but comes with the header soldered on! 16 characters wide, 2 rowsWhite text on blue backgroundConnection port is 0.1" pitch, single row for easy breadboarding and wiringPins are documented on the back of the LCD to assist in wiring it upSingle LED backlight included can be dimmed easily with a resistor or PWM...

This is a fancy upgrade to standard 20x4 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...

Adding a character display to your project or computer has never been easier with the new Adafruit USB or TTL serial backpack! This custom-designed PCB sits on the back of our 'standard' character LCD (16x2 or 20x4 sized) and does everything you could want: printing text, automatic scrolling, setting the backlight, adjusting contrast, making custom characters, turning on and off the cursor, etc. It can even handle our RGB backlight LCDs...

Here is a mini-kit to get your 16x2 LCD standing up straight on your table. Made of 3mm black acrylic pieces, with 4 x 1" nylon screws & 4 x nylon hex nuts, it goes together in a jiffy and looks super-spiffy! This product is designed specifically for our 16x2 USB/Serial backpacks.  Our OLED 16x2 displays and RGB backlight positive and negative LCDs have slightly smaller screw holes so you'll have to drill them out to...

This is a fancy upgrade to standard 16x2 LCDs, instead of just having blue and white, or red and black, this LCD has black characters on a full color RGB-backlight background! That means you can change the background color to anything you want - red, green, blue, pink, white, purple yellow, teal, salmon, chartreuse, or just leave it off for a neutral background. This LCD is the most daylight readable character LCD we have and is very beautiful...

One up your plain old character LCD with a gorgeous VFD! These displays look and act just like character LCDs but are way glowier, and are very readable even from a distance. As a bonus, you only need 3 digital pins to control it as it is a SPI/serial interface not parallel. We have a datasheet for the module and the datasheet for the controller chip (with much more detail in case you need it) These are often used at point of sale machines (at...

When you need low power, ultra-high contrast and any-angle readability, you can't beat these great looking character OLEDs. They are pin/shape compatible with 'standard' HD44780 LCDs. The code is slightly different (they're more timing sensitive) so we have our own Arduino library that plays better with the OLEDs than the standard LiquidCrystal library. Best of all, no backlight or contrast control is required, so they're...
