NRF24L01+ 2.4GHz Wireless Transceiver Module

The Nordic 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, and a 1.9 to 3.6V supply range, the nRF24L01+ provides a true ULP solution enabling months to years of battery life from coin cell or AA/AAA batteries. The Enhanced ShockBurst™ hardware protocol accelerator offloads time critical protocol functions from the application microcontroller enabling the implementation of advanced and robust wireless connectivity with low cost 3rd-party microcontrollers.

This nRF24L01+ chip integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the Enhanced ShockBurst™ hardware protocol accelerator, supporting a high-speed SPI interface for the application controller. The low-power, short-range (~30m) Transceiver is available on a board with Arduino interface and built-in Antenna.

Features:

• 1.9V - 3.6V supply, with 5V tolerant input pins
• 250 kbps (long range), 1 Mbps and 2 Mbps on air data rates
• Built-in 2.4Ghz antenna
• Auto acknowledge
• Auto re-transmit
• Multiceiver - 6 data pipes
• 32 byte separate TX and RX FIFOs
• Software selectable channel from 2400MHz to 2525MHz (125 Selectable channels)
• Simple 8 pin (7 pin without IRQ) SPI interface: VCC, GND, CE, CSN, SCK, MISO, MOSI and optional IRQ.
• Ultra low power

Note - The supply voltage is up to 3.6V. Using a supply voltage of 5V will destroy the module!

Remember - You'll need two of these if you need to transmit and send data between microcontrollers!
