The nRF24L01+ pins function as follows:

• GND – Ground
• IRQ – Interrupt pin. This pin is active LOW.
• MISO – 3.3V-5V tolerant SPI slave output.
• MOSI – 3.3V-5V tolerant SPI slave input.
• SCK – 3.3V-5V tolerant SPI clock.
• CSN – 3.3V-5V tolerant SPI chip select.
• CE – 3.3V-5V tolerant chip enable. This pin toggles the nRF24L01+ IC between transmit (TX), receive (RX), standby, and power-down mode.
• VCC – This is VRAW and is regulated on-board down to 3.3V for the proper functionality of the nRF24L01+. The voltage range on this pin is 3.3V-7V.
