User Manual

Installing an SD card -- make sure the microSD card is flush with the side of the case when
inserted properly. The Pi 3 microSD slot doesn't have a spring as the previous pis did, so if
it's flush with the label outward, it is seated correctly.
3. Connect the ribbon cable to the Pi -- notice that the pin 1 marking is very subtle. Orient the
red stripe on the cable towards the SD card. Alternately, pin 1 can be identified by finding
the missing/beveled corner of the header's silkscreen on the pi.
The pin 1 location and silkscreen is the same between the Pi B+ and Pi B. This image
shows a partially inserted ribbon cable without the case in the way. The ribbon cable is
oriented with the red "pin 1" marking pointing towards the SD card slot.
4. Attach the ribbon cable to the wedge. Pin 1 is pointing towards the FTDI adapter.
