On the , differential pairs (USB 3.2, PCIe) are routed with 100Ω ±5% impedance. The v2 topology introduces curved, chamfered corners instead of 45-degree bends, minimizing signal reflection at frequencies above 5 GHz. is the functional heart of the device, housing

In the center of his workshop sat "The Beast"—a massive, 1990s broadcast-standard CRT monitor that weighed more than a refrigerator. It was a masterpiece of engineering, capable of displaying resolutions that modern screens still struggled to match. But for six months, The Beast had been silent. It suffered from a specific, maddening failure in its input selection matrix. It was a paperweight without the right signal processor. In the center of his workshop sat "The
