NRF 240LO1+ 2.4GHz Wireless Transciever

The nRF24L01 is a highly integrated, ultra low power (ULP) 2Mbps RF transceiver IC for the 2.4GHz ISM (Industrial, Scientific and Medical) band. With peak RX/TX currents lower than 14mA, a sub μA power down mode, advanced power management. A 1.9 to 3.6V supply range, the NRF24L01 provides a true ULP solution enabling months to years of battery lifetime when running on coin cells or AA/AAA batteries. The Enhanced ShockBurst™ hardware protocol accelerator additionally offloads time critical protocol functions from the application microcontroller enabling the implementation of advanced and robust wireless connectivity with low cost 3rd-party microcontrollers.

The NRF24L01 integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the Enhanced ShockBurst™ hardware protocol. The  accelerator supporting a high-speed interface for the application controller. No external loop filter, resonators, or VCO varactor diodes are required, only a low cost ±60ppm crystal, matching circuitry, and antenna.

Connection:
To connect the nrf24l01+ to an Arduino, there are very specific pins that are required. This is due to the serial communications that are required. Fortunately, most of the serial is abstracted away during the code, but the following pins must be hooked up to the same pins on your Arduino; MOSI, SCK and MISO. Vcc and GND are connected to 3.3v and ground, CE and CSN can be attached to any pin and IRQ is not used when communicating with Arduinos.
