Micro SD Card
This documentation includes installation guidelines and sample code for your hardware.
There is a micro SD card slot on the board. This slot adds data logging capabilities to the system.
The slot is a push-pull style which eliminates external card eject.

Arduino IDE includes an SD library by default to access and modify the file system.
