i just got this https://www.ebay.com/itm/5PCS-Mini-SD-Card-Module-Memory-Module-Micro-SD-Card-Module-for-Arduino-AVR-EVE/233095018500
as you can see, its a bit light on description but clearly labeled 3.3V. to connect to a nano, will it be ok to view 3.3v to the 3.3v output on the nano board and the data lines to nano direct? please tell me i don't need level shifters?
thx
FYI, i just connected it and it seems to works after a quick 2 min test, but not sure if its within spec or not
actually, its not really working, i think it draws too much power from the 3.3v reg out on the nano board
guess i'll have to find a 5v micro board
