NRF24L01+ 2.4GHz Antenna Wireless Transceiver Module
- 250kbps to 2Mbit Data Rate
- 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)
Module with a compatible NRF24L01+ transceiver module.
This transceiver IC operates in the 2.4GHz band and has many new features! In addition to the features of the old nRF2401A, it adds some extra pipelines, buffers, and an auto-retransmit feature!
The nRF24L01 is a highly integrated, ultra low power (ULP) 2Mbps RF transceiver for the 2.4GHz ISM (Industrial, Scientific and Medical) band. nRF24L01+ 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.

Pins
While the nRF24L01+ IC has 20 pins available, this breakout board simplifies this down to the 8 pins required to get up and running. The pins function as follows:
- VCC – This pin must NOT exceed 3.6V! Connecting it to 5V will irreversibly damage the board!
- 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.
