RF401 is Norway Nordic company newly protrusive data transmission band 433MHZ single piece wireless transceiver chip, this chip integrates high frequency transmitting, high frequency receiving, PLL synthesization, FSK modulation, FSK demodulation, multi-channel switch etc function, and has excellent performance, low power loss, easy usage etc features. Periphery components of nRF401 are very few, only involve one criterion crystal oscillator and few passive devices without debugging parts, this brings huge convenience for development and manufacture.Table 1 is NRF401 electric performance parameters.Table 2 is NRF401 pin function diagram.
