I have ordered a new soldering iron with some fine tips
I am just waiting on the delivery
i shall try to repair it and will let you know how i get on
thanks again for your kind instructions

Good Evening Community.platformio.org
So i have managed to attach(solder) the wires connecting the Adafruit 5v ready Micro-SD Breakout Board to in place of the damaged/removed SKR 1.4 Turbo Micro-SD Connecter.
using the schematic i uploaded and following the corrections from the kind assistance provided.here…
Unfortunately It is not working !
Diagnostic: skr turbo connected to pc via usb
3. inserting the sd-card -
Can anyone please elude to what may be the issue?
→ SD-BREAKOUT BOARD PIN [CD]
Update
So the marlin SDCard01 USB Device Is available in Windows Device Manager.
i have determined that it was not working previously as
I was working inside a virtual machine instance and the usb was connected to the host.
However :
when inserting the card it can not be read
windows explorer/Disk manager : shows disk but no media
i have validated 3 separate micro-sd cards to ensure not sd-problem
can anyone help?
Success ! The SD-CARD works!
the sd-card will not work until the skr-1.4 turbo is reset!
It was not an issue with the modification or the length of the wiring (I did check). the sd-card also works if the CD is connected to SPI 0.26)
Thank you for all the support without you i would have never worked it out!
i improved my soldering technique as a bonus
the amusing thing is actually that the skr 1.4 turbo sd module was ‘in the way’ in respect to fitting in an extremely tight space in the 3d printer body (its how i broke it)
*i have managed to get it out of the way *
and this will allow more options in placement.
what microscope is that? where can I buy one?
Really interesting topic! I ordered two SD card readers because I thought I could make this work, but both micro SD card breakout boards do not have a CD and CLK pin… I guess that makes them completely useless.
Guess I’ll have to wait for the replacement SMD slot. Managed to order them from China, because literally no Dutch company sells these.
Let’s hope I manage to solder on the new microSD slot haha.
Can you show the pinout of your SD-card breakout board? It might be called differently. Like “DET” for detect instead of card-detect (CD) or SCLK (SPI Clock) instead of CLK.
Thanks for your reply, sadly it only has six pins!
CS
SCK
MOSI
MOSO
VCC
GND
So the pins are literally missing. There are also no additional terminals to solder on for additional functions… What I think it the saddest is that I just bought something that will now spend time in a drawer forever without being used I really don’t like to waste resources. Maybe I’ll find a use for it some day? Who knows.
I’m guessing the CLK pin goes to a pin on the MOSFET to activate the power on maybe.
It’s this model:
Seems to be a HW-125
Here’s more data about this exact card:
This is the SPI clock. CLK, SCLK, SCK, all these names stand for the same thing here. You see SCK1
even being the signal name for it in e.g.
So the only thing you’re missing is the card-detect pin / SDDET. Otherwise you can try the same thing as above. If it doesn’t work, you can try and connect SDDET to 3.3V or GND on start to fake it being detected. You can even connect it to a switch (SPDT style) to switch SDDET between 0V and 3.3V.
Thus I don’t see a reason why this wouldn’t work with the hardware you don’t have.
So with a reference to the above picture and your SD card module, your pinout from SD module to printer board should be
CS → left side of R55
SCK → SCK1 0.7 (on SPI header, yellow wire)
MOSI → MOSI1 0.9 (on SPI header, green wire)
MISO → MISO1 0.8 (on SPI header, yellow wire)
VCC → VDD 5V (on SPI header, red wire)
GND → VSS GND (on SPI header, black wire)
Left side of D7 LED either unconnected or to GND or to 3V3 or to a switch to switch it between GND and 3V3).
Thanks, I didn’t realize SCK was clock, makes sense haha.
So, what would be the problem if I don’t have SDDET? Would I have to perform a special operation when inserting an SD card? I think in that case maybe it’s wise to wait until I receive the actual component before I try this workaround.
That depends on what the bootloader does. We don’t know whether it reads the voltage on that pin at all or if it reacts to it or needs that signal, but it is connected to the microcontroller.
Now either:
Thanks, I’m pretty new to all this. So I’ll first try to connect the microSD slot when it arrives and if that fails I have the backup.
Thanks for sharing your knowledge, it helps a lot to get a bit more insight into how these things work
ps in my country, the Netherlands it’s quite hard to source these things. I only found 6-pin breakout boards. So I’ll have to go on Aliexpress anyway. Then I’d rather wait for the replacement slot to arrive.
