KSZ9031RNX (Gigabit Ethernet PHY, RGMII)

@@ -17,7 +17,7 @@ Why these variants exist: - **Rounded pads (`-RR`)** — every SMD pad becomes a KiCad roundrect (signal pads `rratio` 0.25, EP 0.1), the Altium-style land pattern. A sharp pad corner is a stress riser where copper foil fatigues and peels from the FR4; a rounded corner — like an airplane window — spreads the stress, so the joint lives longer through thermal cycling. - **Combined (`-HV-SB-RR`)** — all three applied to one production-ready footprint. -The family was generated with [footprint-widgets/tools/make-variants.py](https://wiki.adom.inc/john/footprint-widgets), which reproduces the adom-footprint heatsink / solderballs rules.+The family was generated with [component-widgets/tools/make-variants.py](https://wiki.adom.inc/adom/component-widgets), which reproduces the adom-footprint heatsink / solderballs rules.  ## Pinout @@ -49,5 +49,5 @@ Hovering a pad in either widget cross-highlights the same pin in the other (the - **Symbol:** KiCad official library `Interface_Ethernet:KSZ9031RNXCA` (CC-BY-SA 4.0).
