This is a very nice part, that can be easily attached to Arduino systems. I had to dig around a bit to find and configure the correct library (see below) but it works great. 30 Years ago, you would have paid a small fortune for this! I 3D printed a part to mechanically line up the three modules and now use it as one large part with 12 positions.
Here is the most important code:
// Program to exercise the MD_MAX72XX library
// configuration for Nano v3 with 12x 1088AS
//
// Uses most of the functions in the library
#include
#define HARDWARE_TYPE MD_MAX72XX::FC16_HW
#define MAX_DEVICES 12
#define CS_PIN 10 // or SS
// SPI hardware interface
MD_MAX72XX mx = MD_MAX72XX(HARDWARE_TYPE, CS_PIN, MAX_DEVICES);
