It is unclear how pins 2-10 are organized.

Hi,
The pins are organized as shown in the nRF8001-DK HW files (pin 1 is marked on the board):
Best regards,

You will have to check the datasheet of your device to see what is the MIN input voltage for logic high. It seems the Arduino UNO support high inputs from 3-5 V, while the nRF8001 datasheet specifies output high voltage at VDD-0.3 V, leaving you at the edge of the specifications if running without level shifting on your low-to-high lines if VDD of nRF8001 is 3.3 V.
