Mini USB2 4-port HUB (USB-C) was designed to be both compact (30mm x 32mm x 5mm) and low cost. To facilitate such a small size all ports use USB-C connectors.

The USB-C IN upstream port has 5.1k resistors on both CC lines and a 1A poly fuse for power input. The four downstream USB-C ports have 56k resistors on both CC lines indicating "legacy mode" for up to 500mA.

The board is powered by a WCH CH334 USB 2.0 IC

• High performance MTT mode, providing independent TT for each port
• USB 2.0 downstream ports, backward compatible with USB 1.1 protocol specification
• Self powered

Please note whilst this HUB uses USB-C connectors it does not pass USB3 data. The board has pads for a 24C02 on the underside but it's not fully wired.
