Description The NRF24L01 is a single chip 2.4GHz transceiver with an embedded baseband protocol engine (Enhanced ShockBurst), designed for ultra low power wireless applications. The nRF24L01 is designed for operation in the world wide ISM frequency band. An MCU (microcontroller) and very few external passive components are needed to design a radio system with the nRF24L01. The nRF24L01 is configured and operated through a Serial Peripheral 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. Features: Maximum operating speeds up to 2Mbps, GFSK modulation efficiency, Anti-interference ability, Particularly suitable for industrial control applications. 125 Channels, Multi-point communication and frequency hopping to meet the communication needs Built-in hardware CRC error detection, Multipoint communication address control. Low-power 1.9 ~ 3.6V, only 1uA on Power down mode Built-in 2.4Ghz antenna Available software to set the address, only received local Address when output data(Provide interrupt instruction), can be directly connected to a variety of microcontrollers, Software programming is very convenient. Built-in voltage regulator Standard DIP Pitch Interface for embedded applications size: 34mm X 17mm X 1mm Specification: Power supply: 1.9V~3.6V Working current: 13.5mA / 11.3mA output power IO counts: 8 Sensitivity: -85dBm Emission distance: 70~100 meter Data rate: 256 kbps / 1Mbps / 2Mbps Communication mode: Enhanced ShockBurst TM / ShockBurst TM Working mode: Power Down Mode / Standby Mode / RX Mode / TX Mode Temperatures: Operating: -40°C ~ 85°C / Storage: -40°C ~ 125°C Package Included: 1X NRF24L01 Wireless Transceiver Module.
