From the project
Ultimate LED panel. 8x8 matrix. APA102 RGB LEDs
ultim8x8 is an APA102 RGB LED based panel consisting of 8x8 matrix. Panels can be chained to produce larger matrices. Besides +5V and GND, each board requires a CLocK and DATa signal. Each board has CLocK and DATa IN and OUT terminals. When cascading boards, the OUT from one board goes to the IN of the next board.
Each LED can require up to 60mA current at 5V for White light at full brightness. This means driving ALL the 64 LEDs at full brightness White color will require 3.8A Amps. You can get away with lower Amps if you drive LEDs at lower brightness or don't light them all up at the same…
