Grove - RGB LED Matrix w/Driver I2C Address

Hi folks, i have here a pair of new Boards with a stunning Problem.



The first board did Work fine with all the sample Codes.

At my second borad is actual only full blink active.



i test the i2c Address from both boards and the first comes up with 0x65 as should be, and the second shows 0x60 ?



so im not able to display anything else as the britght blue blink on the second board.

the monitor say that they found no board.



is there a bug in the firmware? or broken board?



thanks for reply

Doc

Hi,



Did you change I2C address when you change the board?
