  • are the dimensions of the screen, or with the red outer part as well? Trying to make a compartment for the screen but need to know the exact maximum outer dimensions

  • Sleeper we are having the same problem you had. Still can’t find a solution. What did you do exactly to get it working?
    Hopefully you are still around I realize your post here was a while back.
    If anyone else has an idea feel free to let me know
    Thanks

  • scratch that, I was personally able to get it to work on 3.3V.
    9000: We could not get this LCD to update the display powered with 3.3V in lab. The display holds data at 3.3V, but we had to bring the power up to around 4.5V in order for the display to update.
    Be sure to check page 19 of the datasheet.

  • I have to meet one of the SFE team in real life cos I mean you can see they do an amazing job, I don’t think I could have gotten into electronics without them!!

  • I have both the 3.3v and the 5v versions of this LCD. This might be a dumb question, but what’s the best way to tell them apart? As far as I can tell, the only visual difference is the inspection sticker on the back.

  • Hi, sorry very new at this. Got this 3.3V 16x2 LCD for my first LCD project and hooked it up. Working but any idea why the top two rows of dots are not working? I tried the “hello world” sketch and every character that’s larger than the ‘e’ or ‘o’ is cut off going up. I have it hooked to a pot and if I turn it all the way up the bottom row of 16 is correct, 16 black boxes, 5x8 dots in size but the top row is only 5x6 dots and I can just about make out the tops of the ‘h’, ‘l’s, and ’d’ in “hello world”. Checked voltages, everything looks right. Soldering looks ok for a newbie(nothing loose). Any ideas?

  • I used the serial-enabled version of this display. It worked fine for a week or so. Then I left it for a week in an area that got some direct sunlight. Apparently that killed it, since some commands would no longer work. Later, of course, I read the LCD datasheet that says avoid direct sunlight. Probably an EPROM used for data storage. Be careful to keep it in the dark!

  • I wonder if the same module, but with ROM Code 0x0B could be available in stock. European and Greek characters are often needed for many projects. It’s hard to sit down and store them one by one in the ST7066’s CGRAM…

  • Did you remember to add a trimpot for the Vco input on pin 3?

  • .

  • Yessss! Thanks for stocking the 3.3V version. Any chance you could get some of the 20x2 models as well?
