# Module catalog

Find modules by name or capability, then narrow the results by target and toolchain.
Compatibility reflects module manifest declarations, not hardware validation.
A declaration of **any** matches every selection for that target field.

**All 50 modules.** The filter above replaces this table when it loads.
