 Here's an overview of the reduction in power usage that you can expect from this library. The screenshots below are taken from the nRF Power Profiler application using a Nordic PPK2 while running the blink sketch on the same board.

 > [!NOTE]  
 > Note, this library reduces the power usage of the microcontroller, not the entire board and it's peripherals (Wi-Fi module for example). If you would like to reach the maximum power reduction possible for a Portenta C33 board, please check out the [TurnPeripheralsOff Example](https://github.com/arduino-libraries/Arduino_LowPowerPortentaC33/blob/main/examples/TurnPeripheralsOff/TurnPeripheralsOff.ino) that makes use of the [Arduino_PF1550 Library](https://github.com/arduino-libraries/Arduino_PF1550)
