Pro Micro: Sleep uses 3mA

Post by the_julle » Fri Jul 13, 2018 5:08 am

Hi.


I'm using the Pro Micro, with a 9V battery connected to the RAW pin.
In addition, I'm using the TLC5940 breakout board to supply some LEDs.

I'm using the Low-Power library.
I have removed the power LED, but obviously need the regulator.

When I enter sleep mode, I still have a power consumption of 3mA... Which is a lot more than I was hoping. I know the regulator will be using some, but this guy managed to 0.02 mA, even with the regulator...

Any ideas as to why I use that much power in sleep mode. Is that expected from the Pro Micro?


This is the power down mode I'm using:

Code: Select all

LowPower.powerDown(SLEEP_FOREVER,ADC_OFF,BOD_OFF);

Other components are using power. See this tutorial https://www.gammon.com.au/power

Which components?

As I understand it, besides ADC and BOD, the other modules only apply in idle modes? I'm sleeping in PowerDown mode.
