The scanner sketch miss-reports the device address.
It is difficult to tell much from the photos as they are too blurred.
Were those traces from your code? The data does not look to match what you have posted as your code.
Things to try:-The code on the module's web site.
A different I2C library http://dsscircuits.com/articles/arduino-i2c-master-library.html
It could be you have a faulty module.
Then I put an 8 ohm speaker on the output.
But I didn't think the I2C system would be damaged.
Well you never know what is going to be damaged because you don't know how the die is laid out.
in the range of 200 KHz appear the work just fine; in the range of 60 MHz, the change attempts often cause I2C errors.
Quotein the range of 200 KHz appear the work just fine; in the range of 60 MHz, the change attempts often cause I2C errors.I would definitely say that was a decoupling issue with your layout. Read this:-http://www.thebox.myzen.co.uk/Tutorial/De-coupling.htmlThat is a high frequency you are dealing with and it can get into the supplies. I would also include a 1nF ceramic decoupling capacitor as well as the normal ones.
