Sometimes you need to add a little storage to your projects, and sometimes you need a lot. This TinyShield microSD Adapter lets you add a huge amount of storage by connecting a microSD card to your TinyDuino. And with SD card support libraries included with the Arduino Software environment, you can have your project using microSD cards in a matter of minutes!

This TinyShield incorporates level shifters and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V – no need to worry about damaging your microSD cards if you’re running at 5V.

Note: You need to supply your own microSD card, this is just an Adapter (sorry).
