8GB Regular SD Card (External Memory)
This empty, fast, class 6 or 10 Regular SD card can be used to extend the memory of your controller board by 8 GB. With the Duet, internal memory also serves as the platform for hosting system files and the web interface. This works best with Ethernet file uploads. For changing files repeatedly and physically, we recommend adding this, a regular sized SD card which is used on the more easily accessible LCD port. LCD port needs to be added separately.
