SD CARD SLOT on the Duet WiFi board has broken.

SD CARD SLOT on the Duet WiFi board has broken. If it is used as an external SD CARD Slot Port, inquire whether Wi-Fi connection and config change is possible as an external slot port.

Using the standard firmware, the config.g file must be on card 0, so the internal SD card slot is needed.

If the problem is with the SD card socket itself, it can be replaced quite easily using hot air rework equipment.

Thank you for your reply.
The problem is solder solder pad to replace slot0 is damaged. It is not possible to solder slot0.
How do I fix slot0 when there is no solder pad?
I think I need to connect the sd slot to the pin on the pcb, but I do not know pin out.
I need help.

All the pads of the SD card are connected to resistors, except for power and ground which are connected to a capacitor. So you can make the connections to those components. The wiki has a link to the schematic.

Thank you very much for your kindness.
But I can not find the SD SLOT wiring diagram you mentioned.
I would be very grateful if you could provide us with the link.
I wish you a happy weekend.
