HDD GURU FORUMS

PNY 64GB SDXC. This is new and not available through VNR or PC3K.

Hi, given that the SD contacts are 9 1 2 3 4 5 6 7 8, and 3=GND, 4=VCC

columns are labelled A B C D left to right, and pads rows are labelled 1 to 9 starting from the top. upper left round pad is A-1 for example.

could you test each round pad with both GND and VCC using a DMM continuity beep and show which of the round pads are vcc or gnd? I am thinking this one will be 16-bit bus.

Hi HaQue, sorry for the slow response been one of those weeks. Should be able to get to this tomorrow.

Hey, the only continuity is Vcc at B9. This is consistent with SDHC Type 2, which also only has one Vcc at C7 and no ground. Not sure if that helps is too much ?

Sunny had a pinout like this as I recall
