21 pcs LED 8x8 matrix type 1088AS with Max7219 LED controller (4pcs module from AZDelivery or as a single module from Hailege, Amazon)
With the 4pcs in row modules, there is a little too much distance between the individual LED modules. The modules must be separated (sawn),
and with superglue on the side surfaces of the LED modules are glued together. The individual modules are a bit more expensive, but they do less work because the boards do not stand out beyond the width of the LED modules, and they therefore do not have to be shortened.
Optional for Bluetooth Audio module (Place micro USB port to the outside):
1x Exingk 11x16mm, Micro USB adapter (Amazon, Exing)
1x 0.15mm copper lacquer wire (Reichelt)

The pictures for the components follow:
Optionally, you can expand the RoonMatrix with a Bluetooth audio module.
This is connected to the micro USB port of the Raspberry Zero 2W.
In this case you have to route the micro USB port to the outside, and therefore you need a small micro USB adapter board.
