Want to hook a SD card on to my ESP8266EX

What sd cards adaptors are you guys using (known to work)
What is the max sd card size I can use in the adapter (have an old 16gig) I have read use fat16 or fat32 - if using fat16 sd card needs to be partitioned to 2 gig?

Thanks for the help

I was trying to figure out if I had purchased the right SD Card for my device.

Turns out I was using the wrong set of pins.

So using 16gig formatted fat32 work perfect for me.

UPDATE: In case anyone is using these devices this is how I hooked them up.

When I first tried to hookup the Catalex MicroSD Card to my device (ESP8266EX) I tried the MOSI, MISO, SCLK and CS using the pins in RED.
Just reboots after reboots.

Then I noticed that I had a second set of pins on the other side (BLUE) with the same names when I used the Voi-La worked perfectly.

NOT sure what the or how to use the pins on the Red side. But no matter not needed for this project.

Good to know. Thanks for the heads up

Not playing on writing anything.

I have a P4J program I have written to write Pronto Hex IR codes (as ULongs for B4r) to a file and then am going to use the file on the B4R to hopefully read the codes and call sendIR. Otherwise the memory for the IR codes is too much for the ESP8266
