I have a project with an Arduino Nano, GPS Module, SPI SSD1306 Display, and a micro-SD module. I am trying to replace the micro-SD module because it is 5V only. All parts are working properly under 5V.
I purchased a Spakfun
DEV-13743 because it was listed as being compatible with 3.3V systems. However if I connect it to the Nano any sketch does not recognize the sd card.
Plus if I connect the DEV-13743 the display gets corrupted after a few seconds
Attached is a diagram of the original circuit
I have the dev-13743 connected as follows:
VCC to Nano 5V
GND to Nano GND
CS to Nano 4
DI to Nano 11
SCK to Nano 13
DO to Nano 12
Original circuit diagram attached
Any help is greatly appreciated
