Search the Adom Wiki for the library component "ULN2003A" (slug: uln2003a) at https://wiki-ufypy5dpx93o.adom.cloud/wiki/libraries/uln2003a. 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 ULN2003A is a 7-channel Darlington transistor array with integrated suppression diodes. Each channel sinks up to 500mA. Commonly used to drive stepper motors, relays, and LED arrays from logic outputs.
