I'm running out of ideas to sort my issue out.
I can get my micro SD card reader to connect to a nano, but I cannot get it to connect and write to the card from an Uno.
The card reader I have is:
I am using the CardInfo example sketch.
I am wired as follows:
SD Reader NANO
GND GND (29)
VCC +5V (27)
MISO D12 (15)
MOSI D11 (14)
SCK D13 (16)
CS D10 (13)
I'm not using any pullup/down resistors on the Uno or the Nano.
I've tried 2gb, 16gb, 32 gb cards, all formatted using SD Card Formatter 5.0.2. They all can be written to using the Uno.
I keep getting the usual errors when using the Nano,
15:22:14.366 -> Initializing SD card...initialization failed. Things to check:
15:22:16.504 -> * is a card inserted?
15:22:16.549 -> * is your wiring correct?
15:22:16.549 -> * did you change the chipSelect pin to match your shield or module?
I've tried three different nanos including one new one
Is there something stupid I'm missing, or is there something odd about Nanos that I don't know?
