From the project

A "SLuper SLimple" USB 2.0 Hub on a 1-square-inch board, using the SL2.1A IC

A 4-port USB 2.0 hub on a 1-inch (25.4mm) square board. Utilizes the (hand-solderable) SL2.1A USB Hub Controller with footprint for an optional crystal oscillator. Features length-matched data lines for maximum potato-performance.

Uses only surface-mount components and, except for the IC and (optional) crystal, all of them can be found in your parts bin or scavenged from other equipment.
