How to control led cube with Raspberry/Arduino?

Question

Arduino

Good day! There was a need to assemble an LED cube under the control of Raspberry / Arduino (preferably Raspberry Pi, since it is available). Making your own PCB is not an option. There is a desire to buy a ready-made kit ( ru.aliexpress.com/item/3D-LightSquared-DIY-Kit-8x8... ,searchweb201644_5,searchweb201560_1)
It, as I understand it, has some kind of pre-installed microcontroller. And having collected the whole set, in principle, you can already finish it. But I need control with Raspberry . The power cable has a USB interface on one side. What happens if you connect it to the Raspberry Pi and thus provide power and control it at the same time? (Of course, with the help of certain software).
Who thinks about this? Thanks :)

Answer 1

it can and will turn out in such a cube at one time, most likely only one row of 8 LEDs is lit. the maximum should be 20mA * 8 = 160mA usb usually outputs up to 500mA.
I made a homemade 4x4x4 cube on an arduino where at one point in time only one 20mA LED lights up there.
In such cubes, control is quite complicated, in my opinion. Find out first if there is software for this cube.
PS I reviewed the list of parts for this cube and saw 9 pieces of 74HC573, which potentially makes it possible to burn 64 LEDs at once, and this is more than 1.2A, which is more than it can withstand, depending on which work algorithm they have chosen.
It may be worth looking for a cube in which the possibility of controlling it via usb is indicated.

Answer 2

need extra. food, not enough power. The voltage will drop so that it will cut out)
Usually they do this: they connect to the arduino and send values ​​​​from the disassemble (for example, via uart), and the arduina controls according to the specified conditions (values).
