This board requires the use of a backpack to operate. Currently the only developed backpack is the ESP32 module.
(no interactive BOM here, unfortunately)

This board is large, expensive and relies on pick-and-place assembly to get right. (I mean, you can TRY to solder 1,044 LEDs manually, but even doing 100 is a giant pain).
Since this board pushes the limits of most fab houses (just on size), it's worth reaching out to them by email to see if they can support.
I can confirm the following fab houses can build this board.
