B4R Question WeMos MicroSD Shield Pinout?

Hi - I'm looking for some help with connecting a MicroSD shield to a WeMos D1 R2. I thought the correct pinout was:

D1 -> SD
SS/D8 - D8
MOSI/D7 - D7
MISO/D6 - D6
SCK/D5 - D5
3V3 - 3V3

However now the board that I connected to seems to be toast. On bootup the SCK LED comes on, but then goes out & stays out & I can't seem to successfully connect to the board via the USB cable.

Any ideas?

Thanks - Colin.
