consumption.



When measuring current under the condition of maintaining voltage at 3.0V, external DC power source

powers chips instead of onboard power supply.



When measuring power consumption, disconnect UART and SWD with debugger to avoid additional

impacts from debug device.

2.3 6-axis Motion Sensor

6-axis motion sensor is powered by VDD_DEV, so J6 needs to be connected before using G-sensor.

If I2C interface is applied, J18 and J19 should be shorted with jumper. That is to say, connect I2C signal line to

M3_2 and M3-3. INT single line can be connected to M2_2 via J20, and can be left not connected if INT function

is not configured.

If SPI interface is applied, R1 need be removed. Connect test point AD0 and nCS to specified IO port with SDO

and nCS jump wire respectively, and then short J18 and J19 with jumper.
