NRF24 DRAWING TOO MUCH CURRENT

I am trying to make a remote control with NRF24 and Atmega328p. The full name of the NRF24 I am using is E01-ML01SP2. I fixed everything but it draws too much current. I have a remote control made by someone else and it draws 10 mAh but mine draws 70mAh. I am using Arduino IDE as a studio. I want to share my transmitter software with you.

  • And what current does the device show in sleep mode versus when it's running? 70mA is more than the nRF24 series is able to draw by itself, so there must be either some leakage current or some other device on your PCB that is drawing current in addition to the nRF24 on your design. Have you checked what the Atmega device is drawing in terms of power here?

    Best regards,
