Member: 396421 Status: Offline Thanks Meter: 87 | to understand it correctly: as you write 2.8=3.3 this means that my adapter can reach also the maximum value of 3.3V, yes? br Gesendet von meinem GT-I9100 mit Tapatalk |

Member: 396421 Status: Offline Thanks Meter: 87 | furthermore on the emmc pinout of the samsung N8000 which i have uploaded in the first post shows pins for vcc and 3.3V. according to your answer it is vcc = 3.3V. so a mistake in the pinout? vcc is supposed to be vccq? or how is this pinout to understand? br Gesendet von meinem GT-I9100 mit Tapatalk |
