Makerbase MKS Slot2 V1.0 + RepRapDiscount Full Graphics LCD + RAMPS 1.4

I want to add an external SD card adapter on my RepRapDiscount Full Graphics LCD. My 3D printer is based on (Arduino Mega + RAMPS v1.4 + RepRapDiscount Full Graphics LCD).
I buy an SD Card Adapter from Aliexpress (https://www.aliexpress.com/item/32873382195.html?spm=a2g0s.9042311.0.0.4f544c4d5UzB1L) and now I want to add this adapter on my RAMPS 1.4 while not disturbing the working of RepRapDiscount Full Graphics LCD.
Please guide me how can I add this to my RAMPS? Thanks!

You will need to find (or create) a list, that shows how the pinout of the connectors on the SD card board.

Then you need to pair the pins to the AUX-3 pins on the RAMPS 1.4 shield.

And finally you need to decide on how to connect/solder the wires together.


The easy solution for you, would be if someone already had a LCD adapter, with an extra 10-pin socket on it, so it would be possible to connect both the RRD LCD and the MKS SD card connector. But I doubt such a thing exists. So perhaps you might want to try to design one yourself?

Or you might want to upgrade your LCD solution to a MKS TFT35 or MKS TFT70
