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

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 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.

The displays work as described.

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.

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!

Neither screen displays at all. The backlights appear to not be working. U1 gets too hot to touch on both screens, so I know power is flowing through the device just not to the LCD.
