An Introduction of Transceiver NRF24L01

Introduction

The nRF24L01 is a low-power, single-chip 2.4GHz transceiver with an incorporated baseband protocol engine (Enhanced ShockBurstTM). The nRF24L01 is designed to operate in the 2.400 – 2.4835GHz ISM frequency range across the world. To create a radio system with the nRF24L01, you’ll need an MCU (microcontroller) and a few external passive components.

A Serial Peripheral Interface is used to configure and operate the nRF24L01 (SPI.) The registration map is accessible via this interface. The register map comprises all of the nRF24L01’s configuration registers and is available in all of the chip’s operating modes.

The integrated baseband protocol engine (Enhanced ShockBurstTM) uses packet communication and may operate in a variety of modes, ranging from manual to sophisticated autonomous protocol operation. Internal FIFOs guarantee that data flows smoothly between the radio front end and the MCU of the system. By handling all high-speed link-layer tasks, Enhanced ShockBurstTM lowers system costs.

GFSK modulation is used at the radio front end. The frequency channel, output power, and air data rate are all user-configurable factors.

The nRF24L01 can support a data rate of up to 2Mbps over the air. The nRF24L01 is ideal for extremely low-power designs because of its high air data rate and two power-saving modes. Internal voltage regulators offer a high PSRR and a broad power supply range.
