waveshare RGB Matrix Multi-Features Digital Clock for Raspberry Pi Pico, 64×32 Pixels 2048 RGB LEDs, Accurate RTC,3mm Pitch Allows Displaying Text/Image

The 3MM pitch 64x64 panel has a labeling mistake. Pin 'D' is mislabeled as 'GND'.I couldn't get the library they suggested working, but ESP32-HUB75-MatrixPanel-DMA works fine on this panel. In the example "2_PatternPlasma", I just had to set 'E' to 32 and it worked.

The panels are very nice but the factory packaging provides no corner protection for the display. I'm not referring to the packaging that amazon uses to ship, but rather the box that the displays are packaged in from the factory. I ordered two panels and BOTH had the exact same broken pixel on the corner. Both displays have a damaged dead pixel on the corner. It is silly that they can't provide a little more foam on the SIDES of the box to protect against this.I did plug the panels in and the rest of the panel looks very nice. I'm using a Teensy 4.1 and Smartmatrix display driver. I've arrange the two 64x64 panels side by side to create a 128 pixel wide by 64 pixel high panel. The panels provide a very nice bright image and I didn't see any issues with these other than the two dead pixels due to shipping damage.The included hardware for mounting was not very helpful for me. The screw in studs have only a magnet on the end. So unless you are going to mount this on your fridge, you'll need to provide your own standoffs and hardware.It did include a ribbon cable to connect to your display driver (or chain between panels) and also a breakout ribbon cable. The power cable provided includes TWO panel connectors, so this is ideal if you chain two panels together like I did, but leaves one dangling if you only intend to use a single panel.

Worked just fine.Some differences in brightness with one I bought before

Fired it up and rows 3 and 31 dead

This did not come with all the wires and backing that is shown in the product photos. Also notes that there is a guide to connect to your raspberry pi, this is also nonexistent. Put your money somewhere else, very disappointed.

The media could not be loaded.  Colors are off setting are right colors super off

it is useful for some projects not so much for other projectsfor it to work with the project I puchased it for I need to do modifications that it took me a while to find

👍

Good build quality and clear and no faulty leds on this package. Used for hoby and experimentation. The included diffuser does the work nicely. Cables included were good quality and also the magnetic stands with bolts etc

So I tried to follow the wiring from the tutorial and many differents types of arduino sketches for the ESP32 and it would never work.. A total ripoff
