      [h2]
      At the different modes, and with different peripherals enabled, how much power does SuRG42-CP consume?
      [/h2]

      Below you will find a list of SuRG’s power consumption during operation under different modes:

      Input Current

        Idle: 1.4mA (Images on the display are visible)
        Idle, w/ Touch Wakeup: 2.6mA (Images on the display are visible)
        Active: 24mA (Able to update images on the display)
        Active, with Frontlight: 61mA
        Power Down: 30uA (MCU powered down)

      Input Power Consumption

        Idle: 4.4mW (Images on the display are visible)
        Idle, w/ Touch: 7.7mW (Images on the display are visible)
        Active: 71mW (Able to update images on the display)
        Active, with Frontlight: 184mW
        Power Down: 80uW (MCU powered down)

      System current consumption fluctuates based on peripheral utilization and display writes.
      Characterization shows a current variation of ±6% (Idle) and ±11% (Active) relative to reported averages.
