nRF2401A nRF2401A is an improved model of nRF2401 (nRF2401AG is a lead-free process model). nRF2401A works in the 2.4GHz international ISM application-free band GFSK modulated wireless data transmission chip. The maximum transmission power is 0dBm, the receiving sensitivity is -90dBm, and it supports 124 receiving frequencies and 126 transmitting frequencies. It uses ShockBurst transmission mode and has two independent data receiving channels. It supports air data rates of 250kbps and 1Mbps. It uses the SPI interface and MCU to complete data communication and communication control functions. nRF24L01 nRF24L01+ (nRF24L01P) is an improved model of nRF24L01, which has the same wireless characteristics and operation mode as nRF24L01, and also adds 250kbps air rate support. NRF24L01/NRF24L01+ is a new type of RF transceiver device produced by NordicVLSI of Norway. It adopts 4 mm×4 mmQFN20 package. NRF24L01/NRF24L01+ operates in the ISM band: 2.4～2.524 GHz. It has built-in frequency synthesizer, power amplifier, crystal oscillator, modulator and other functions, and integrates enhanced ShockBurst technology. The address, output power and communication channel can be configured through the program, which is suitable for multi-machine communication. NRF24L01/NRF24L01+ has very low power consumption. When transmitting at a power of -6 dBm, the operating current is only 9 mA; and the corresponding receiver operating current is only 12.3 mA. Multiple low-power working modes (power-down mode and idle mode) make energy-saving design more convenient. The industry-leading low power consumption of NRF24L01/NRF24L01+ makes it particularly suitable for 2.4G applications powered by button batteries. The entire solution including link layer and MultiCeiver functions provides more functions and lower power consumption than the existing nRF24XX. Compared with the current Bluetooth technology, it provides higher speed while consuming less power. The newly adopted nRF24L01+ is compatible with nRF24L01 and adds 250kbps low-speed function.

The industry-leading low-power NRF24L01/NRF24L01+ is particularly suitable for 2.4G applications powered by button batteries. The entire solution including the link layer and MultiCeiver function provides more functions and lower power consumption than the existing nRF24XX. Compared with the current Bluetooth technology, it provides higher speed while only consuming less power. 9. The open communication distance is about 60 meters, and the indoor communication distance is about 30 meters.
