This Micro SD card adaptor allows you to easily use gigabytes of flash memory with Teensy. It can also be used on a breadboard, or with almost any AVR processor.

A 3.3 volt regulator and 5 to 3.3 volt buffer chip protects the SD card, and allows interfacing to 5 volt processors. Technical documentation is available in the Teensy reference section.
