Power the Wayne holder using the USB connector on the board and don't connect the UNO. Then put 5V to pin 10, 11 and 13. Check if the output has 3V3 on the DWM1000, SS (10) goes to pin 1, MOSI (11) to pin 2 and SCKL (13) to pin 4, counted from the USB connector to the antenna and on the side of the R2. The code published on GitHub for the arduino-DWM1000 open source project I'm using to drive the DWM1000 module was designed to work with the Arduino Pro Mini and hard coded to use interrupt 0 which, in the Pro Mini, is on pin 2. However, on the Pro Micro, interrupt 0 is connected to pin 3 and pin 2 uses interrupt 1.
