The NRF24L01+ is a single chip 2.4GHz transceiver with an embedded base band protocol engine (Enhanced ShockBurstTM), 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. You can operate and configure the nRF24L01+ through a Serial Peripheral Interface (SPI). The register map, which is accessible through the SPI, contains all configuration registers in the NRF24L01+ and is accessible in all operation modes of the chip. 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 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. Inter-modulation and wideband blocking values in NRF24L01+ are much improved in comparison to the NRF24L01 and the addition of internal filtering to NRF24L01+ has improved the margins for meeting RF regulatory standards. Internal voltage regulators ensure a high Power Supply Rejection Ratio (PSRR) and a wide power supply range.
