Hello, I'm using nRF52833 MCU board for my project, I have to do power optimization to my project(Device). In my device two sensors are there, and boost regulator and buck regulator and EEPROM. Heart rate 5 click (IC :- AFE4404 and sensor number :- SFH7072) & Accel 5 click (IC :- KX132-1211) Now I'm getting 4mA without code and 9mA with code, and I have to convert to in µA. But i don't know how I'll do it? I was try to add "sleep_mode_enter()" in the last of main function But still same result. Can anybody suggest me how to do it power optimization ? Thank You,

power Optimization for nRF52833

Hello,

I'm using nRF52833 MCU board for my project, I have to do power optimization to my project(Device).

In my device two sensors are there, and boost regulator and buck regulator and EEPROM.

Heart rate 5 click (IC :- AFE4404 and sensor number :- SFH7072) &
Accel 5 click (IC :- KX132-1211)

Now I'm getting 4mA without code and 9mA with code, and I have to convert to in µA. But i don't know how I'll do it? I was try to add "sleep_mode_enter()" in the last of main function But still same result.

Can anybody suggest me how to do it power optimization ?

Thank You,

Hi

My colleague Jeff has a great power optimization guide for nRF52 series devices here, that should take you through all the most common ways to optimize power consumption in your nRF52 design. Without knowing what exactly your design does, or how much these sensors are expected to draw, I think you should be able to get way lower than 4-9mA on average current consumption, as that is a lot.

Best regards,

Simon
