Arduino pro mini sleep Mode power consumption

Projects General Guidance

Hi

I am using arduino pro mini with NRF24L01 to transmit data from one device to another.
I have removed LED of pro mini.

In transmission mode i am getting 10mA, But the problem is in sleep mode i a getting around 5mA which is not good.

Can someone please check the codes and help me what is wrong and what changes i should make.

codes are in the attachment

If the transmitter has a sleep mode, use it as well. Else cut off the transmitter power supply during sleep.

3

Remove the regulator from the Pro Mini and run it at 8 MHz and ~3V battery power. That will get the current consumption to microamps or nanoamps during sleep.

See this solar powered Arduino/NRF24L01 project for ideas.

Disable the Pro Mini VCC LED as well.

I have removed vcc led of the pro mini. But I have not removed voltage regulator but working with 3v 8MHz.

Is everything fine with the code? Do I need to make any changes?

What is the sleep current now ?
