Once hooked up to a USB port (GND, D+ and D-) and a 3.3 VDC power source Linux will show it as follows:
Note: Only VDD is required. Not sure what the P0.5 (a GPIO on nRF24LU1+ chip) is used for (maybe for power-on?). I’ve measured ~22mA at 3.3V power consumption.
Warning: USB provides 5.0 VDC. That’s probably going to break the chip if you hook that up to VDD (not sure, didn’t try.. :-). Use some LDO or maybe 3 diodes to get the right voltage. On the Raspberry PI you’ll find 3.3 V on one of the headers.
