Upload any of the examples included in the Gamebuino library. Youāll end up in the title screen. Press the C-Button and it should flash the LOADER.HEX located on the SD card. This way you can test if it works

I asked because I havenāt re-soldered the display: if there are problems anyway Iāll have to detach it
Iāll make something tonight/tomorrow lets see
@0x1001, youāre making things way too complicated.
This looked like a simple soldering issue to me as there is no way there could be 4 unconnected traces on the PCB.
- you didnāt have to desolder the SD socket and connect the wires directly to the SD card
- Desoldering the screen was unnecessary and not a good idea
My suggestion is that you send us your unit and I will fix it and return it to you.
Well desoldering was my last resort, I tried many things but it wasnāt working
Thank you guys for the assistance, Iām going to ship it monday

Ok, please update me after you ship the unit. I will try to look into it and fix it ASAP.

Got back the Gamebuino this morning and it works fine, youāre awesome!

Iām glad that this is solved, I was personally fixing your device and the solution was quite simple - I just replaced the SD card socket.
I am still not sure what caused the issue, maybe it was caused by the SD socket being defective in the first place or was damaged in the transportation/assembly process.
Anyways, thank you for your patience and supporting MAKERbuino!
Iāll mark the topic as solved.
Keep making !

I had a problem with the SD card too. I found this thread quite helpful, but the image above, with the wiring, seems to be wrong. Also the numbering on the PCB is wrong, isnāt it? The pins should be 1 to 14 and 15 to 28, right?
@ben_el_dude, the pin number is wrong, you are correct.
We will correct that in Q1 2019ās hardware update.
Thank you for your understanding
