ESP32-S3-A7670E-4G

I'm trying to write and read from the sdcard, in the code snippet that follows I have doubts about how to define the pins of my esp32-s3-a7670E-4g

sck=machine.Pin(18), mosi=machine.Pin(23), miso=machine.Pin(19))# Initialize SD
cardcs = machine.Pin(5, machine.Pin.OUT) # Chip Select (CS) pin
Someone could help me with pin matching?
thanks a lot for your help

Hi,

I never seen a pin definition like "machine.Pin(xx)". It might be correct or not.

Please tell us what IDE, compiler + version, libraries you use.

You working with a C++ lib that has GPIO object control ? Or micropython ?

My guess is (Micro)Python going by the "#" for the comment and the use of the 'machine' module (e.g. https://docs.micropython.org/en/latest/library/machine.Pin.html)

Your ESP32-S3-A7670E-4G module uses the SDMMC interface (not SPI) for the TF (microSD) card.
