External Micro SD access upgrade
This kit will allow you to access the Micro SD card on the outside of the case. The kit can be used with the Raspberry Pi mounted in either of its two mounting positions.
Peel off the tape backing of the small 3D printed part and install into the ribbon cable slot as shown below.
If mounting the Raspberry Pi as shown below, insert the short extender into the Raspberry Pi micro SD slot and it will extend the card to the outside of the case. Use the long ribbon cable to connect the display to the DSI slot as shown.
If mounting the Raspberry Pi in this position, peel the tape off the PCB and mount the PCB inside the raised edge of plastic as shown by the red line in the image below.
Use the included long ribbon cable to connect the display to the DSI slot as shown.
