Value 4 Port 1A USB 2.0 Hub Module
If you need a simple four port USB hub inside a custom enclosure or in your project, then this Value 4 Port 1A USB 2.0 Hub Module from PMD Way fits the bill.
The hub has a USB A plug on one end and four USB A sockets, and supports both USB 1.1 and 2.0 standard.
Designed user-input devices such as mice, keyboards, numeric keypads, webcams and so on. The hub's power is drawn through the USB A plug so your total hub draw can't exceed 1A - so not for external hard drives etc.
