AZDelivery 5 x PCD8544 84x48 Pixel Black Character White Background LCD Display Module 3.3V with Backlight for Nokia 5110 and PS2 Joystick Gamepad, compatible with Arduino Including E-Book!

I just love AZDelivery since I found them. Not only does their product come exquisitely packed but they have full information online as to how to use the product including wiring diagrams and programming examples.They will be my first port of call for future Arduino and Rpi components.

Brilliant is all I can say, nostalgic love it

I've taken a standard Micropython library for these displays, driving them from a LoLin32 (also AzDelivery). At first I connected just the lower display, but when that didn't work properly, I added the upper one in parallel with it, which should be fine for this test.One display stays blank, the other has a speckled pattern. When I send the invert command, the lower screen inverts, but stays speckled, the upper one stays blank. The pattern is the same every time I run through inialisation which I take to mean that the internal RAM is faulty.The backlights work and one is clearly responding to at least one command, but that's it. I don't have high hopes for the other 3 in the box as I've already got a 100% failure rate.

Purchased these after another source supplied a faulty one. 3 of these arrived in a box with no packaging inside. This meant they were free to move around and subsequently scratched the metal frame. The displays do have a protective cover on them but I’m not sure if that will always be effective. My displays worked fine and had no issues.

If you order these screens don't expect them to work straight out the box. I ordered two at different times and both had the same fault. You have to apply great force to the screen at the bottom then reset your arduino. in order of them to turn on. As both had a loose connection.

Got these to have 1 LCD which I already had mounted and 1 for testing. However, none of them work!!!Tried everything to get them working, but no display. Yet when trying my LCD (Identical to these) it works fine in the breadboard.Do not recommend, these faults are likely due to them not being protected when shipping. They come in a box without any sort of protection.

A bit of faffing with Arduino but got there in the end. If you're buying please note. These run on 3 volts use resistors on everything but the vcc and vdd lines which are 3 volts only. Ps one display malfunctioned but the four metal securing tabs on the back were loose if this happens bend them over and solder in place. Happy days !!
