Arduino nRF24L01+ and MOSFET Wiring

flux

0:57

I've inserted the following components into your schematic:
  • The nRF24L01+ module (designator U2) connected as follows:
    • VCC to the Arduino U1 3V3 pin
    • GND to the Arduino GND
    • CE to Arduino digital pin 9
    • CSN to Arduino digital pin 10
    • SCK to Arduino digital pin 13
    • MOSI to Arduino digital pin 11
    • MISO to Arduino digital pin 12
    • IRQ left unconnected
  • The MOSFET circuit has been added by inserting:
    • The IRLZ44N MOSFET (designator Q1)
    • A 470Ω resistor (designator R1) between Arduino digital pin 6 and the MOSFET Gate
    • A 10kΩ resistor (designator R2) from the MOSFET Gate to GND (to serve as a pull-down)
The wiring for the MOSFET is as follows:
