MAX7219 Microcontroller 4-in-1 Display Dot Matrix Module For
Specifications:
A single module can drive a 8x8 dot matrix common cathode Working voltage: 5V Module size: 12.8 x 3.2 x 1.3 cm (L*W*H) With 64 fixing screw holes, hole diameter: 3mm Module with input and output interfaces, support for cascading multiple modules
Wiring:
1. The left side of the module is the input port, and the right is the output port. 2. Control of a single module, the input port only need to receive CPU. 3. The more a module cascade and input end of the first module is connected with the CPU and input end of the input end of the output end is connected to the second module, output terminal of the second module connected with the three modules, and so on. For example: 51 SCM VCC→5V GND→GND DIN→P2.2 CS →P2.1 CLK→P2.0
Package included:
1 x MAX7219 Dot Matrix Module 1 x 5pin Dupont Cable
I first tried the dotMatrix on the Arduino with the Sprite and Matrix libraries. I got funny results because the column adressing is reversed.
Therefore I switched to the MD_MAX72xx libraries. Make sure to change the define in the MD_MAX72xx. h file to read:
#define USE_FC16_HW 1
I used the MD_Keyswitch library found at https://github.com/MajicDesigns/MD_KeySwitch
and the MD_MAX72xx library found at https://github.com/MajicDesigns/MD_MAX72XX
Then I pulled the source at https://github.com/MajicDesigns/MD_MAX72XX/blob/master/examples/MD_MAX72xx_ScrollChart/MD_MAX72xx_ScrollChart.ino
With that you should be able to get it to work.
If you use pins that are not-SPI standard, make sure to activate the call to MD_MAX72XX with four parameters, and comment out the one with two parameters.

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

@***** look it up in the MAX7219 datasheet. Another cool thing about these ICs is the need for just one resistor to limit the current for all segments x digits (64 per IC) to retain the same brightness whether only one LED is on or all 64. IIRC there's a chart there with recommended resistor values depending on number of LEDs. I could probably lift one of the 8x8 matrices off and see what resistor value they've used, but the datasheet should give you an idea. Assume you need an external power supply though. They're not super bright but it's still 256 LEDs.

Q:
Can I daisy chain several of these? By just connecting output of the first with input of the next?

Depending on how much you want to daisy chain you should inject supply power every 2 or 3 modules else the voltage drop and the current running through the modules gets to high

Depends on what you mean by "users manual". The datasheet for the MAX7219 controller is excellent and all you need to know to program these things. If you want plug and play there are multiple libraries to choose from.

Q:
I can choose the color of the matrix or only send it in a single color?

Use the MD_MAX72XX library. With the device set to: #define HARDWARE_TYPE MD_MAX72XX::ICSTATION_HW. If you don't change that line in the examples, the characters are mirrored. Use the MD_Parola library (also) for even more functions. All sketches have to include that line, the default is Parola hardware.
