This post is just to document the placement of the pins on my breakout with the extender; the Sparkfun breakout board ( coming soon ) has a slightly different layout.
Note: Vss in the pic above (ground) is normally the third pin up from the bottom, between D0 and CLK. I moved Vss physically to create two logical groups of three pins PF0-2 and PF3-5; this also allows for good separation between Vdd and Vss.
Note: See schematic pp 9; T-card/USB
Code:
Pin SD SPI
PF5 D2 X
PF4 D3 CS
PF3 CMD DI
+ VDD VDD
PF2 CLK SCLK
PF1 D0 DO
PF0 D1 X
- VSS VSS
