    very good product and good price. If you don't know how that work i found one good tutorial. https://www.makerguides.com/max7219-led-dot-matrix-display-arduino-tutorial/ If you try the programs and see that they do not work with the first one. Try changing the names of the pins you will use and reload the program on Arduino. e.g. CS_PIN 10 DATAPIN 11 CLK_PIN 13

    Very good. Proper old-school red led matrix. Four modules on one board which could be cut apart if required, perhaps to make a 16x16 instead of 32x32. This daisy chained with the last one I bought and is working well. The picture shows it just pushed together at right angles with the last one for a quick test. Brightness set to zero is quite bright still, and possible to run marquee powered via an Arduino Nano. Be warned, at full brightness and all on (e.g. test mode), this willl likely draw too much current for that configuration. Ensure that the power is applied to the module at all times as the logic lines will try to drive it if VCC becomes disconnected. The connector that's already soldered in is a bit of a pain, but not too hard to de-solder and replace. The LEDs are socketed, which is handy for altering the inter-module connection arrangements. The first of these I bought had arrived with one of the sockets sloppily manually soldered, which caused one of the modules to sit a bit wonky, and meaning I had to do a bit of reworking. I shall certainly be buying a few more of these.

    It would be practical if we could see what pin is without remove the matrix LED
