Which pin is CS on MKR SD Proto shield?

Development Tools IDE 1.x

Dear everyone,
Please forgive the probably trivial level of these two questions but I seem unable to find the answer unaided:

My ambition is to log data from a barometric sensor on a SD card, using an Arduino Nano and the Arduino MKR SD proto shield.

  1. It appears from the tutorials, examples etc I have studied that there has to be a CS or SS connection between the board and the SD shield to initiate communication.

A pin-out map tells me that the Nano CS pin is no 10, but where should it go on the shield?

  1. What is the difference between SCK and SCL pins on the SD shield? I thought that SCK =SCL?

Many thanks in advance, every useful answer is gratefully appreciated! //Erik

EDIT
you can't use the MKR shield with classic Nano. Nano is a 5 V board and MKR shields are for 3.3 V MKR boards. you will damage the SD card

Thanks! I´ll try that!

you can't use the MKR shield with classic Nano. Nano is a 5 V board and MKR shields are for 3.3 V MKR boards. without logic levels shifters you will damage the SD card and the flash memory
