Two Grove IMU sensor (v2.1)

#1

I would like to connect these two Grove IMU sensor to Arduino or Wio terminal.
Is it required to change the I2C address for one of these two grove sensor?
How can I do that? soldering is needed? or any other method possible?

Hi @youngil_sohn, You can use the address jumpers to switch the I2C address,

877×509

  • 1: MPU-9250 I2C address select Pad, default connected a and b address is 0x68, if connect b and c address is 0x69
  • 2: MPU-9250 interrupt pin, the interrupt should be configured, available interrupt sources are: motion detection, fifo overflow, data ready, i2c master error

I cannot try but I can try in the near future.
Thank you very much.

Great, let us know after trying out.

With soldering machine and connect b and c. and I tried the followings;

#include “Wire.h”
#include “I2Cdev.h”
#include “MPU9250.h”

MPU9250 accelgyro(0x69);

However in this case it doesn’t work.
However with default setting (0x68) it works.

Is there more things to do?
