Hi everyone,
Do I need to buy three power supplies for the arduinos? Or is everything powered by the 5v power port on the main PCB itself?
Thanks,
E

In my experience, you do not need additional power for the arduino boards.
You only need to power the PCB (actually all those LED displays) with an external 5V power supply.
I tried a common USB charger (with 2A current output) for mobile phone which seems to suffice.
But you will need a USB to 2.1mm DC plug cable.

I just finished soldering and want to thy this bad boy out  I'm going to order a 5v- 2a power supply from Amazon since we are on complete lockdown. |
