23、 with an embedded baseband protocol engine (Enhanced ShockBurst), suitable for ultra low power wireless applications. The nRF24L01+ is designed for operation in the world wide ISM frequency band at 2.400 - 2.4835GHz.To design a radio system with the nRF24L01+, you simply need an MCU (microcontroller

24、) and a few exter- nal passive components.You can operate and configure the nRF24L01+ through a Serial Peripheral Interface (SPI). The registermap, which is accessible through the SPI, conta accessible in all operation modes of the chip.all configuration registers in the nRF24L01+ and isThe embedded

25、 baseband protocol engine (Enhanced ShockBurst) is based on packet communication and supports various modes from manual operation to advanced autonomous protocol operation. Internal FIFOs ensure a smooth data flow between the radio front end and the systems MCU. Enhanced Shock- Burst reduces system

26、cost by handling all the high speed link layer operations.The radio front end uses GFSK modulation. It has user configurable parameters like frequency channel, output power and air data rate. nRF24L01+ supports an air data rate of 250 kbps, 1 Mbps and 2Mbps. The high air data rate combined with two

27、power saving modes make the nRF24L01+ very suitable for ultra low power designs.nRF24L01+ is drop-in compatible with nRF24L01 and on-air compatible with nRF2401A, nRF2402, nRF24E1 and nRF24E2. Intermodulation and wideband blocking values in nRF24L01+ are much improved in comparison to the nRF24L01 a

28、nd the addition of internal filtering to nRF24L01+ has improvedthe margfor meeting RF regulatory standards.Internal voltage regulators ensure a high Power Supply Rejection Ratio (PSRR) and a wide power supply range.Revision 1.0Page 7 of 78nRF24L01+ Product Specification1.1FeaturesFeatures of the nRF
