Search the Adom Wiki for the library component "MAX7219" (slug: max7219) at https://wiki-ufypy5dpx93o.adom.cloud/wiki/libraries/max7219. Pull down the KiCad symbol, footprint, and 3D model files from the wiki page's assets. Install them into my current KiCad project and register in sym-lib-table and fp-lib-table. If the page has a datasheet URL, save that too.
The MAX7219 is a compact serial input/output display driver from Maxim. Drives up to 8 digits of 7-segment displays or a 8x8 LED matrix. SPI interface with built-in BCD decoder and brightness control.
