HiLetgo 2pcs HD44780 1602 LCD Display Module DC 5V 16x2 Character LCM Blue Blacklight New

The displays work as described.

Bought this to use when building a new QMX+ transceiver from QRPLabs. It works great. I have another QMX+ with the yellow background. But I’ve not yet tackled replacing that screen. But, the blue screen with white letters works great in the new build.

This is a good product at a great price. However, they are not serial LCD's, they are parallel. Their customer service is outstanding and was willing to work with me on the problem and have followed up to make sure I was happy. 4 stars for the product and the customer service, 1 star off for the misleading advertising. Would definitely buy from this company again.

This LCD display works really great when paired with the Arduino Uno. In my opinion, the only thing that would make it even better is if the header pins were already soldered to the board. I suppose the manufacturer doesn’t do this, so that they could be used in a different application.

For the price, I was not expecting much, but I was surprised by how well they worked. Both of them were functional, once I figured out how they worked. A better instruction sheet would have been nice. They will never fly in a spaceship, but for what I needed for my home project, they are well worth the money.

Character LCD displays end up in a lot of my projects. These displays are high quality parts that function flawlessly. I bought this particular pair specifically because it did not have an I2C adapter; I wanted a parallel interface for the particular project I was working on.

This is a well made unit and has good contrast and brightness. Price is right for the quality. It doesn't have header pins which can be an advantage if you're going to solder wires directly to it. If you do want header pins they're easy to attach.

I used one of these displays to replace one that failed in my iCharger 106b+ that I use for my model airplane batteries. I love that charger, it's served me very well over the years, but the display started showing random characters and kept getting worse to the point where I couldn't really read it sometimes. For less than the cost of shipping on a new charger, I got two new screens and replaced the one in my charger, and it's good to go! I've got a spare too just in case I need it for this or a future project... lol Good stuff!

Ok

One is working great, the second one the back light flickers after a few minutes then goes out. The text is still showing just no back light. If I turn it off for a bit and turn it back on it works for a bit then flickers and the back light goes out again. It was easy to get these working on my Arduino UNO R3 and the fist one has been working great so far. Update:They both seem to be working now 5 Stars! Fast delivery thanks!

Excellent product worked with standard library for both Great Cow BASIC and Arduino. With Great Cow BASIC being a lot fast to operate the LCD. The soldering of the connector was fast with the PCB being very clean as the packaging is good. Overall - very good. Details of my tests - I attached to an HiLetgo R3 UNO. - Using the same code logic for Great Cow BASIC and Arduino C. Cleared the millis counter to 0: Print a test value to the LCD: Move the cursor on the LCD: Print millis() on the LCD - Great Cow BASIC was sub 1ms with the Arduino at sub 4ms. The backlight is good and the build quality is also good. For the code used to test please review the attached picture - or, look in GitHub for 'HiLetgo' and optionally add 'Anobium' to the GitHub search. I am not affiliated with HiLetgo. I am the developer of Great Cow BASIC - an open source compiler for AVR and PIC MCus.

A standard 1602 display perfect for arduino projects. I’ve bought quite a few over the years and have yet to see any difference in display output. I always go for the QAPASS stamped ones only because that was the first one I bought many moons ago and I suspect they originate at the same factory. A good quality robust display with a nice bright backlight. Backlight can, in my experience, be driven by PWM output (larger displays draw a higher current and won’t run from an arduino PWM pin) so you can adjust brightness and contrast via pwm pins if you want software control rather than external pot or resistor. Solder leads to the display or use pins if you plan to use on multiple projects. Works just fine with the arduino LCD library. At the time of purchase this was the cheapest prime for a pair I could find.
