NRF24L01 + 2.4GHZ Wireless Transceiver module for Arduino

1 low working voltage: 1.9 ~ 3.6V low voltage operation 2 high speed: 2Mbps, due to the transmission time is very short, greatly reducing the collision phenomenon in the wireless transmission (air transmission rate software set 1Mbps or 2Mbps) 3 multi frequency: 125 frequency points, meet the multipoint communication and frequency hopping communication needs 4 tiny: built-in 2.4GHz antenna, small volume, 15x29mm (including antenna) 5 low power: when working in answer mode communication, air transport and starting time of fast, greatly reducing current consumption. 6 low cost: the NRF24L01 integrates all the relevant RF agreements and high-speed signal processing, such as: automatic retransmission of lost packets and automatically generate a response signal, SPI interface, NRF24L01 can use the hardware SPI port connection or by SCM I/O port simulation, internal FIFO and all kinds of high and low speed microprocessor interface, easy to use low cost microcontroller.
