hello.
i searched a lot of posts on the web, but couldn't solve my trouble.

first of all, i use Arduino Micro.

i want to change my imu's i2c address from 0x68 to 0x69.
i found some ways to solve it.

i connected AD0 pin to 3.3v for expecting that i2c address is 0x69. but there is nothing change.
my imu data is still not on address 0x69 but on address 0x68.

i check i2c scanner, also, but this is the same result.

what should i do?

i have connected pull-up resister on AD0 pin....but failed.

help me please.....

Did you break the solder jumper connection to GND on SJ2?

Oh... i solve the problem!!!! i can use another address 0x69 now.
i really appreciate your help!

so how to connect？
which pin should I connect with SD0 VDDIO?

appreciate your reply。

Jumper SJ2 does the whole change. Break the default jumper and solder jumper to the other pad.

What‘s the meaning of the whole change？ Isn't it sj1(VDD connects to VDDIO ) sj2 (AD0 connects to GND)? I read the document which says connect to AD0 PTH to change externally, and pull high to set address 0x69. I can't really understand what meaning of this word........

appreciate your reply..
