How many clarifying questions would you like me to ask? I'll start with one:
Do you intend to replicate the WS2812B-Mini component multiple times (and if so, how many and in what configuration: a single row, grid, or another pattern), or do you have another LED type or configuration in mind?
Please let me know if you'd like to provide further details or have additional questions.
To create an 8x8 LED array, you can replicate the WS2812B-Mini component 64 times and arrange them into 8 rows and 8 columns. In Flux, you can use the duplicate and alignment tools on both the schematic and PCB layout to facilitate positioning them in a grid pattern.
Please let me know if you need any more details on the spacing or net connectivity for the LED array.
