F7 Power Consumption Test [Copy link]

    The F7 board does not have an IDD interface for users to test the power consumption characteristics of the MCU, so it can only measure the power consumption of the entire board. The problem is that the LCD is always on, causing the current to exceed 200mA. I can only switch to the 20A range for measurement, but the accuracy is reduced if the range is too large. I planned to turn off the LCD screen. Fortunately, there is a control port for controlling the LCD backlight, as shown in the figure below, just pull the control port down.

Power consumption in normal mode

Power consumption of the board in SLEEP_MODE

Power consumption of the board in STOP_MODE

Power consumption of the board in STANDBY_MODE

Power consumption of the board in STANDBY_RTC_MODE

Power consumption of the board in STANDBY_BKPSRAM_MODE
