"The media could not be loaded. I've been looking for a large, bright, easy to program display and these work great. Using an Arduino Uno to test with, hook up GND, VCC to +5V, CLK to pin 13, DIN to pin 11, and CS to pin 10. I recommend using the MD_Parola and MD_MAX72xx libraries. Install them from "Manage Libraries..." in Arduino IDE. Lots of examples included. Just make sure for this particular part, specify:#define HARDWARE_TYPE MD_MAX72XX::FC16_HWHappy programming!"

I just wish it was a 4 pack so I could make an even 1x4, 4x1 or 2x2 stack of them as one big display the only option here is one wide line or an awkward 1x3 stack which results in 3 rows of 4 columns just roughly too small for an extra row of usable font but not small enough to evenly place he desired font center. I’m thinking I’ll use one for a separate project and 2 stacked on top each other for a single large line or 3 medium line displaym czapla

They need to offer the same item but without the header pins already installed. Removing them is difficult and can easily damage the very thin traces on the board.chameleon

For the price, I had to try these...About 15 years ago, I looked at something like this and was turned off by the $125 price tag. It is awesome how inexpensive these have become.I've tried these with Arduino and with ESPHome. It is very nice that the libraries for both include a brightness setting from 0 to 15, cuz they can be painfully bright. I will be using at least one of them for advertising/notices pointing outside and will probably set them to 15 when I deploy them, but as I poke around with the code on the workbench, I set them to brightness setting 1 and it's still pretty intense.It's the libraries I've found, but so far they all have two identical weaknesses - when the text scrolls, the code removes all whitespace at the end of the string. This means the last and first words touch as it repeats the scroll. Both libraries also pause for almost a whole second when the message restarts.sherm

I was looking forward to this, based on the user pictures posted. I really need Amber/Orange, not red, and the pictures posted at the time of my order were perfect. But I got red. :( So it's not useful for me. Seems to work as expected, but it's the wrong color.warren b futrell

I have quite a few 4x8 LED modules. When trying to desolder the pins so I could solder them together with wires the vias would come out with the pins, making the module useless without soldering bodge wires.To prevent ruining all of my 4x8 displays, I ordered two of these modules. One module was for a project at work, the other was a spare just in case issues arose with the first one.Fortunately they did not have header pins soldered to the PCB. I soldered wires to the input through holes to dupont connectors, then made an extension cable to connect it to a Arduino Nano clone board.No setup was needed for the module and it is compatible with Arduino and MicroPython. The display is quite bright but that can be adjusted through code. The module was the perfect size for displaying several digits without having to g to solder two 4x8 modules together.The price is slightly more than a 4x8 module, but you avoid all of the issues with trying to desolder header pins and not removing the vias then soldering them together with wires.What Customers Talk About
