Highly recommended display

Bright and easy to use; However, you must have the correct Arduino/ESP8266 driver. I used LiquidCrystal_I2C.h. You also need to play around with the pot on the back to get the best display. Bright and pleasant to look at. I'm using some homemade barometers with BME280 with ESP8266. Bezels are available on Tindie.com, search Bezels on Tindie.

Pros
  • Positive only
Cons
  • No insurance

good display - bad packaging

I use enough displays from 2004 for a product I make. I usually buy them from another seller. It wouldn't surprise me that they are all made in the same factory. I ordered these 2 packs because I --- need 2 displays! The pins were bent and one of the pins was missing the LED/POWER jumper. The packaging of the order was terrible. The packaging on the displays could be appropriate if they were packaged properly from the start. Saving a few dollars didn't make up for the 45 minute troubleshooting.

Pros
  • cool product
Cons
  • I vaguely remember

Pretty good displays compromised by lack of quality assurance

I felt like I really had to write this review. I am working on an Arduino project and have purchased a total of four of these two displays. I have two of these that are DOA and one with a bad line in it. That's 37.5% of infant mortality from the FACTORY! Number two. These displays are terribly packaged. Because of this, they were all received with bent pins. I'm not sure how this would affect point one above. I'd love to recommend them, but it's difficult due to the factors above.

Pros
  • Complete set
Cons
  • Annoying

Nice display, great price

I ordered a pair of these displays to use with the Arduino. One of the two came with no jumpers, the pins are slightly bent and the plastic film on the display is damaged which made me suspect a return, but it worked perfectly and once I removed the protective film the display itself was in good condition Constitution. The I2C integration was trivial. Basically connect 4 wires from the display to the Arduino (it has enough power to drive the display, no problem), plug in the LiquidCrystal_I2C…

Pros
  • Price
Cons
  • Lots of stuff

Expect reliable customer service!

Dear Customer Service, Thank you for your quick response to my problem.

Great display at a bargain price from OUTSTANDING SELLER

These displays are very popular and extremely easy to use with Arduino. They come with and without an I2C backpack. This particular seller is offering 2004 pairs (with backpacks) at a very high price so I bought two pairs. One of the units had a small problem with the backpack - it wouldn't turn on the LCD backlight, although the LCD backlight itself worked fine, I was able to turn it on by powering it directly from the edge connector on the 2004 PCB. So I emailed the seller (JANSANE) and asked

Pros
  • Not cheap but decent
Cons
  • Upgrades

Same issues as previous reviews

Poorly packaged, bent pins, backlight jumper missing. By setting a jumper and aligning the contacts, the display worked. It worked fine on my Arduino connected table for about a week and then stopped showing data. I can reset or upload to Arduino but the display doesn't show any data. Luckily it was 2 packs so I put the backup display up and running and it worked fine. I'm concerned about the durability of the display. I will update this review if it dies too but so far not impressed with…

Pros
  • Fingers crossed
Cons
  • Crumpled packaging

It's great now! best in computers and accessories

EDIT; Well the seller exceeded my expectations; under their warranty and will now send me two replacement screens free of charge. This is a perfect example of great customer service, five stars from me. (OLD REVIEW BELOW) I bought these 2 screens to help me with my school project as I thought an extra screen as a backup would be great but it's a problem. At first the screens were packaged horribly, most of the pins were bent, but after some fixing/bending I was able to test them. Luckily both…

Pros
  • Excellent design
Cons
  • Not as good as it promises
