See the preview image and the PDF file for more information.
The nRF24L01 is a single chip 2.4GHz transceiver with an embedded baseband protocol engine (Enhanced ShockBurst™), designed for ultra low powerwireless applications. The Device is designed for operation in the world wide ISM frequency band at 2.400 – 2.4835GHz. An MCU (microcontroller) and very few external passive components are needed to design a radio system with the nRF24L01.
The Device is configured and operated through a SerialPeripheral Interface (SPI.) Through this interface the register map is available. The register map contains all configuration registers in the nRF24L01 and is accessible in all operation modes of the chip.
The embedded baseband protocol engine (EnhancedShockBurst) is based on packet communication and supports various modes from manual operation toadvanced autonomous protocol operation. Internal FIFOs ensure a smooth data flow between the radio front end and the system’s MCU. Enhanced Shock Burst reduces system costby handling all the high-speed link layer operations.
