Power consumption analysis

Use DISCO-L562QE board

An Energy Meter is embedded in DISCO-L562QE (STM32L562E-DK)

SW tool is STM32CubeMonitor-Power

Change to do in the DISCO-L562QE board side

  • top side: SW1 switch has to be moved from VDD to MEAS
  • top side: JP4 switch has to be moved from 5V_STLINK to 5V_PM_USB (position 5 to 2)
  • top side: JP2 switch (IDD) has to be removed
  • power board with USB CN16

Change to do in your target

  • remove IDD JPx switch

Connection

From DISCO-L562QE/PM_EXT_MEAS white connector (CN20), there are 4 pins: pin 1 (closest to A0) to pin 4

  • Pin 1 has to be connected to GND of target board
  • Pin 3 to one of IDD pin of target board
