Micro SD Card/Unmount Button

The SD Card can be used for Data Logging in the project.

When an SD Card is inserted, the “uSD” LED will flash green a few times then stay on steady green.

The “Unmount” button is pressed prior to removing the SD Card. When pressed, the uSD LED will flash momentarily during the unmounting process. When the uSD LED turns off, this indicates it is safe to remove the SD Card.
