Easy Raspberry Pi expansion with new USB hub

Published: 25 April 2013 - Rachael Morling

Cyntech Components has announced that first production samples of its Pi-themed USB hub design have completed formal evaluation and approval by the Raspberry Pi Foundation. The company will have units in stock from May.

Cyntech’s powered, 4-Port USB Hub addresses a problem commonly encountered when trying to add peripherals to the Raspberry Pi computer, namely the number of USB ports.

Dave Mellor, managing director of Cyntech Components, explained: “The single-port Model A board clearly has limitations but even the two ports of a Model B board are frequently taken up by the computer’s keyboard and mouse. This means if you want to connect any other USB peripheral, such as an external storage device, camera, printer, etc. you will need a powered USB hub to expand the number of available connections.

“A powered hub is also necessary when using any USB device that requires more than the 100mA current that can be supplied by one of the Pi’s USB ports. And, a further benefit of a powered hub is that it can be used to power the Pi computer through the board’s micro-USB port, saving on the need for a separate mains adaptor.”

The Raspberry Pi USB hub is shaped and embossed in the form of the Raspberry Pi logo. It has four USB ports arranged around the raspberry body with the power supply connection between the leaves.

The hub meets the full USB 2.0 ‘Hi-Speed’ specification for data rates up to 480Mbps with three of its ports supporting continuous loads of 500mA and in-rush currents up to 800mA. The fourth port, which provides power to the Raspberry Pi, is rated at 1A to ensure sufficient power for the board and its connected devices.
