Hi, is it possible to connect this to Arduino Pro Mini 3.3V 8M3.3V328 directly?

Can this MicroSD card slot works with the Beetle ESP32 C6(SKU:DFR1117)? Thanks.
If it does not support, How could I add MicroSD card slot to Beetle ESP32 C6(SKU:DFR1117)?
JaneYu Don't count on anything bigger than 4G with an 8-bit microcontroller, but you should be able to use any card fully if you're using a 32-bit microcontroller.
JaneYu It is perfectly compabible with that processor's hardware, but you may have a hard time getting the firmware crammed into such a small space.
JaneYu That's silly. That potential customer is trying to do a new PC layout, so they need a physical drawing of this module.
JaneYu LOL. Replying to myself.
Issue resolved.
SD card attached to SPI bus as follows:
* Mega: MOSI - pin 51, MISO - pin 50, CLK - pin 52, CS - pin 53 and pin #53 (SS) must be an output
JaneYu Where can I find the dimensions fo this MicroSD card. I searched a lot but didn't manage to find that kind of information. (By dimensions I mean the pins, their distance from the edges ect)
JaneYu The pins are exactly 0.1 inches (2.54mm) apart. Referring to the 5th photo, the MISO pin is 0.16 inches (4mm) from the left edge and all pins are 0.1 inches (2.54mm) from the bottom edge.
You'll see the overall dimensions clearly printed ^^^. "20x28mm(0.79x1.10")"
The working voltage of the SD card module is 5V, 3.3V microcontroller can not provide sufficient voltage for it.
JaneYu Is there a version that can work with the Pro Mini 3.3V. The reason is that the Mini 3.3V will also connect to a 64x128 pixel LCD display. (this will be a Billboard for a Model railway).
