Good product. Excellent datasheet for the MAX7219 controller making it fun writing your own library. Serial interface is pretty much SPI. Data is transferred in 16-bit words (8 bits register address + 8 bits register data). Since there are 4 devices chained together (one for each 8x8 matrix) it basically becomes a 64-bit shift register where each command word "trickle" down the chain. A no-op command is used to skip a device or to shift existing commands in the chain to the next device and to the next and so on. Have fun!

Θα ήταν πρακτικό αν μπορούσαμε να δούμε τι είναι η καρφίτσα χωρίς την αφαίρεση της μήτρας LED

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