Description: This is a basic 16 character by 2 line display. Black text on Green background. Utilizes the extremely common HD44780 parallel interface chipset (datasheet). Interface code is freely available. You will need ~11 general I/O pins to interface to this LCD screen. Includes LED backlight.

Dimensions: 3.15" x 1.425"

  • Bought this one and it was perfect for what I wanted. Basic inexpensive LCD that worked great with the Arduino.

  • Any tips on getting the 4.2V for the backlight? A simple voltage divider circuit isn’t ideal because the load from the backlight.
    Is 5V gonna kill the backlight?

  • This was very easy to use with an arduino; if you are interested I have written a tutorial on how to do so:

  • The easiest way would be to stick a transistor inline with the power lead of the lcd and turn it off just before the cpu goes into the low power state.

  • This product worked great. I wrote a tutorial about manually writing data to the display using dips switches and push buttons.

  • Completely useless, I have no idea what happened but when I wire it up according to the tutorial on arduinos site for the Hello World! LCD program, nothing but the backlight comes on. Also the pins are flipped from where they are in the schematic. Total cluster fuck of a product. EDIT: So apparently the product works fine, and I apologize to all those at sparkfun. I should be on the arduino forums tell them that the tutorial is a cluster F**k and not this item. for those who had the same problem, you have to connect pin 15 Vin and pin 16 to GND, everything on the tutorial is correct.

  • Does anyone know about the six extra pins on the right side

  • I just realized I forgot the bridge connections over the cnter of the breadboard to actually connect the data lines to the LCD. It works now I think I need to adjust the contrast or something. The text on the display is more visible when looking at the display from an angle.

  • I just bought this and thought it had the HD44780 chipset but now I started looking at the datasheet for the pin interface descriptions and I realize that it has the KS006U chipset? Is the datasheet wrong or is the sparkfun description wrong? Or maybe they are basically the same chipset? I’m confused right now. Do I need to buy a different LCD? Steve

    • HD44780 is more a standard that a chipset at this point. there are tons of different chipsets that use the same protocols. like how people say “allen wrench” instend of saying hex key. HD44780 is the LCD equivilent of X86 instruction set. the cool think is you can lean how to use the 16x2, and then use the same code on everything from 8x1 to 40x4 displays.

  • Can be found for less than 3 $ incl. shipping on Ebay:

    Search “16x2 LCD” and tick “Worldwide shipping”, “Buy it now”, and select “Price + shipping: lowest first”.

  • What if: You purchased this part, the item received is a red sparkfun pcb, and the sticker on the back reads: ADM1602k-FSY-YBS/Z. Plugged 5V into it according to the example code within the arduino IDE, and one of the LCD drivers burned up. (the larger circle).

    I’m trying to figure this out, but I can’t verify that the board is actually supposed to take 5V or 3.3V. Maybe next revision should have this printed on the pcb :0)

    Thanks for any help

    • Totally agree! SFE, can you please print the voltage on the PCB? Otherwise, there’s no way to tell the 5v and 3.3v boards apart by looking at them, except for the inspection sticker (assuming you haven’t removed them).

  • New to LCDs? Use the LCD 16x2 simulator availavle here:

    You can simulate data on each pin of the HD44780 compatible LCD and see how it works, or if you are more advanced you can write directly your own scripts in the web browser to control the LCD, same as you would use them in the MCU code

  • When will these be in stock?

  • Is there a flat cable assembly available for these? I’m OK using the 0.1" headers, but the electronics I need to hook up requires a cable interconnect. And I’d like it so that I can replace the LCD without desoldering it.

  • I?m considering using this in a battery powered device that will experience long periods of inactivity. During the inactive periods all system components will enter a low power stand-by or sleep state. This display does not appear to have a low power (uA) state.
    The Kent display has a low power state but it?s two large for my application. Does anyone know of a LCD display with a low power state?

    • This is a very late response, but anybody in this situation can simply connect the LCD in series with a MOSFET. YOu can then switch the LCD on and off from a microcontroller. Remember to leave all the microcontroller outputs floating because power can still flow into the LCD if you keep these in certain states.

  • works great! still trying to figure out a good way to mount it though…Any Suggestions?

    • Hi,
      There are four mounting holes to use. I would recommend you figure a way to tie into those.

  • Totally useless product

I received and tested. Your product is really nice. This is what I exactly want it. Thanks for quick shipping and supporting.

A wonderful product, just don't forget the header!

I forgot when purchasing that this does not have pins on it to plug into a breadboard and I didn’t have any headers at home. I cut the leads off of some rarely used resistors and soldered them in for this. Not exactly how it was meant to be done, I don’t think, but it worked for me!

Of all the Basic 16x2 Character LCD's I've owned...

This the the one.

Works as described. Gave me an excuse to visit the new Sparkfun building. Very nice!

Works fine.

I have just used the 16x2 LCD display with the DG-5 emulator and it works fine. No problems whatsoever! I’d probably buy some more.

Works great

No complains. Easy to setup. Worked on the first try (I use an mbed board and the TextLCD library did all the work for me),
