This adapter is a vertical shield. It has a socket so the pins are accessible if the attachments are compatible. It only connects to the AREF to D8 eight position socket, which does not have power, so it requires a jumper from 5V(VCC) to one of the slots on its dual socket, so as to replace the 5V socket with another one. It also has a 1 port card detect (CD) socket, which can be jumpered to another available pin on the Arduino.
It is modeled to support the SD CardInfo example included in the Arudino IDE. Chip select (CS) is connected to D8 with a jumper, it can be moved to D9 or D10. It can be used simultaneously with the Ethernet non-shield.
