Modulo a matrice di punti MAX7219 modulo display a LED 4-in-1
8,79€ 13,83€

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

BG346351252 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

D: Dumb question- I'm new to all this: Do I have to buy the leds and solder them all myself or are they already installed in the "board"?

BG346351252 Theboard is completly assambled except for the pin-headers used for the connection. Those have to be soldered by yourself
