A list of UHS-II SD cards, readers, and cameras

For those of you not in the know, most current SD cards implement an Ultra High Speed bus (which is abbreviated UHS-I or UHS-1) because it is the 1st version of this bus. It has a maximum transfer rate of 104MB/sec. Since there are some cases which require higher transfer speeds, the SD card consortium has created a new bus called UHS-II (or UHS-2.) The difference is two-fold:

  1. UHS-II raises the maximum transfer rate up to 312MB/s.
  2. UHS-II uses an additional row of pins/contacts to get there.

uhs-i-vs-uhs-iiThis means that UHS-II cards can only be fully utilized if the device using it has physical support for these extra pins/contacts. If the device does not have these extra pins (and that’s pretty much all devices as of 2014), then the SD card will fall back to UHS-I mode.

The best Arduino starter kits compared and reviewed

The Arduino is arguably one of the best things to come to the “Maker” Renaissance that we are currently experiencing. The Arduino is a simple microcontroller that can allow the one who wields it great power and programmatic control over their electronic circuits and systems. Yet to be a great wizard of such things, one must start at the humble beginnings of the very basics.arduino-angledWhat better way to get started than with an Arduino starter kit? That’s the trick, though, isn’t it? There’s more than one starter kit out there!
