Pi accessories from Farnell ... USB chargers?

morgaine

Selecting "View all accessories" from Farnell's Pi "Register your interest" page doesn't show a single USB charger.  Using the search function isn't too successful either, as most of the hits are for car chargers.  I found only one micro-USB charger in (minimal) stock, and that didn't even have a datasheet link provided.  Perhaps there are others, but I didn't find them.

 

This situation isn't too great.  The quality of micro-USB supply is absolutely critical for proper Pi operation.  Ideally I'd like to see Farnell evaluating a number of chargers for us and offering high-current and well-regulated chargers as Pi accessories.

  • Hi all,

     

    Just seen this - anecdotally, we've been using this poweredpowered USB hub (as expansion ports and power supply) at exhibitions to demo the Raspberry Pi and it has worked really well.

     

    We've also been using smart-phone chargers (in particular for BlackBerry) which have also been more than capable.

     

    To be fair we've probably not been pushing the Pi to its limits though. The heavy power consumption really seems to come from driving the GPU to its limits, so I expect it would be in these cases where you need to pay particular attention to the current delivery of whatever PSU you're using.

     

    Hope this helps, again, it's only our own experience from exhibitions and demonstrations so I can't speak for all cases.

    edit - made the product link work.

    @Joe,

     

    The data sheet for that part says it is a Bus powered hub but the Farnell listing says it comes with a UK plug. Does it have an external supply and what is it's spec ?
