This is an 8 gig microSD memory card. It's perfect for massive datalogging without taking up a lot of space. These microSD cards have a simple to use SPI interface allowing any micro to read and write data. It even comes with an SD card adapter and a USB adapter!

Works perfectly! love the compact usb reader! I'm using this with the mp3 Trigger to attach with the illumitune mini I replicated from the tutorials, now my son can play his favorite song and play along!
This is, what is now, a small and slow SD card. It did work to load and run the Raspi Jessie version on my RPi B+, which was what I was trying to do after having trouble with two other Kingston 16Gb SDs from another source. But in the course of the investigation I also bought a different 16Gb Class 10 (faster) card at Office Despot for less than the cost of this kit. Also this card was slightly smaller (~7.5Gb) than my original RPi 8Gb card and thus would require re-partitioning of my dd'ed backup file to just copy across.
