⚡Install this component
Paste this into Claude Code (VS Code panel, Adom editor, or terminal) to install:
Search the Adom Wiki for the library component "TDA7492P" (slug: tda7492p) at https://wiki-ufypy5dpx93o.adom.cloud/wiki/libraries/tda7492p. 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 TDA7492P is a 25W+25W dual BTL class-D audio amplifier from STMicroelectronics. High efficiency (90%+), wide supply range (8-26V), and excellent audio quality. Used in high-power Bluetooth speaker boards.
