Writing to SD card on Adafruit Bluefruit nrf52 feather

Hey guys,

I’m trying to write to an SD card using my nrf52832 using the SD library. According to the schematic, the SPI clk, MOSI, and MISO port pins are 12, 13, and 14 respectively. I looked through the Sd2PinMap.h file and none of the possible board types define the pins like that. How am I supposed to set this to have the proper SPI pins to communicate on those pins?

Thanks!
Charles
