Mine are the black ones:
I changed the ce and csn pins in the mirf example to 9 and 10 (what I used for the rf24 library) so I didn't have rewire when changing libraries.
I'm powering mine off the 3.3 pin from the nano. The specs for the nrf24l01+ nRF24 Series - Nordic Semiconductor - nordicsemi.com only show a 13.3mA draw
