Designed for Adom workcell USB distribution.\n\n## How It Works\n\nThe three USB-C 2.0 connectors are the primary user-facing interface for this molecule. J1 (upstream) connects to the USB host; J2 and J3 (downstream) connect to USB devices. The downstream ports provide power delivery to connected devices via per-port power switches (AP22615) with overcurrent protection.\n\n**All input power comes through the machine contacts only** — the hub does not draw power from the upstream USB host. The workcell +5V rail feeds in through MP1/MP2 and MC20–MC22, powering the hub IC, the 3.3V LDO, and the downstream port power switches. This self-powered topology means downstream devices get full 5V power from the workcell supply regardless of what the USB host can source.\n\n## Overview\n\n| Property | Value |\n|---|---|\n|
