Power supply and cables for daisy chained LED matrix

Post by adoptabot »

I have some students who want to put together an LED display for student council to post messages.

So far, they want:

2 - 64x32 RGB LED Matrix - 5mm pitch displays
1 - Adafruit RGB Matrix HAT + RTC for Raspberry Pi - Mini Kit
1 - Female DC Power adapter - 2.1mm jack to screw terminal block

They are going to supply their own raspberry pi with power supply.

The questions are:

What power supplies are needed to run the two boards and matrix? Can the boards and matrix be powered by adafruit's 5v 10amp supply, or do we need separate power supplies for everything?
What cable do we need to connect the displays together? (Looks like IDC, but they come in different configurations...)
Are there other things we will need?

Some general info on powering the display's is here:

and specifics on using them with the RGB HAT here:

Yes, that would work. Read the linked guide above for more details.
What cable do we need to connect the displays together?
Use the ribbon cable that comes with the display.
Are there other things we will need?
I think you've got the main parts covered. You'll need some tools (soldering iron, solder, wire cutters) for assembling the RGB HAT:
