Hi, th Error message or Error Code is generated by the SdFAT System to the terminal. Have you select the correct SS pin of SD Card which is correspond to the example arduino sketch? either D3 or D10. SD card format need to be in FAT32 or 16 and pls copy the sta013.cfg into the SD card for initialization of STA013 after the SdFAT initialize. If you have further inquiry, please do discuss in our technical forum as this section is for short inquiry, thanks :

We already check the connection of d3 and d10. but the error keep coming.
btw,what is the meaning of this :
"pls copy the sta013.cfg into the SD card for initialization of STA013 after the SdFAT initialize."
how do we initialize STA013 after the SdFAT?

So, which did u select for ss actually? Which sample code you download to the arduino uno? Copy sta013.cfg means download the file from Cytron website product page and copy the file into ur microsd card. Make sure your microsd card is formatted as fat32. I hope u can show us a photo of your setup. Power the arduino with external power instead of usb
