Cyntech – USB Hub addresses common problem encountered when trying to add peripherals to the Raspberry Pi (Raspberry Pi)

Cyntech Components has partnered with Pimoroni to have its Pi-themed, USB Hub manufactured at Pimoroni’s facility in Sheffield, UK. Fully tested and endorsed by the Raspberry Pi Foundation, the PiHub is featured in a promotional video on the company’s website.

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. As 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.”

Cyntech’s Raspberry Pi USB Hub is both practical and attractively styled. Shaped and embossed in the form of the Raspberry Pi logo, the hub has four USB ports arranged around the raspberry body with the power supply connection between the leaves. Rubber feet on the bottom make it less likely to slide around on a desk or other work surface. 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, with sufficient headroom to support in-rush currents when external hard drives and the like are connected. The fourth port, which provides power to the Raspberry Pi, is rated at 1.1A to ensure sufficient power for the board and its connected devices, says the company.
