nRF401 typical application circuit is shown in the figure, UDD uses +3 V power supply. The R1, JT, C1 and C2 constitute the crystal oscillator circuit, C3, C4 and R2 form the loop filter. R3 is the power setting resistor. C5 is decoupling capacitors for power, C6 and C7 are de-noising capacitors. DIN, DOUT terminals are respectively connected to Microcontroller TXD (serial output), RXD (serial input) side. For simplifying the circuit, nRF401 and μC can be combined with a crystal oscillator circuit, the circuit is shown as below. X1, X2 are the crystal μC input and output, the oscillator frequency is directly added to the nRF401 end of XC2.
