This is a 4GB microSDHC card (SDC44GB) that comes with a SD adapter and is pre-programmed to contain the latest Google Coder distribution image.
These microSDHC cards use the new speed "class" rating of Class 4 that guarantee a minimum Data transfer rate of 4MB/sec. We may ship a Sandisk or Kingston card, both are high quality and come with the same speed class rating.
Adafruit tests and verifies each card before shipment. This image can be downloaded directly from the Coder Website Downloads Page.
