UM2+ SD card reader

[si2w 8]

Hello,

It seems that I broke the SD card reader. It worked well since 2013. Now the printer crash when trying to read a SD card.

I tried :

- 4 different SD cards with various speeds => FAILED

- format them is FAT32 => FAILED

- flash again the last stable Tinkergnome firmware. Flashed successfully but didn't solved the issue

- flash again the last stable original UM2+ firmware. Flashed successfully but didn't solved the issue

The UM2+ is still working with the USB cable.

My conclusion is that the SD card reader is probably broken.

Someone knows which manufacturer / part number they use ? It's not mentioned in the BOM on github.

I don't know if there are more details in Altium. I cannot read the files...

Thanks

Best,

Circuit maker can open altium files, but I use mac and it’s only for windows

Could anyone take a look to help?

Software free to open the files

What does that writing on the component say? Probably a part no. one can find on the web?

There might just be some dust or hair in there blocking contact with one of the pads.
