PCA9685 IOT I2C not working with additional PCA9685

Hardware
1

When using the PCA9685 with the USB to I2C IOT Adapter I cannot connect a second PCA9685 to the chain successfully. I2C scan results in all addresses being returned. Address was 40 for first unit and 41 for second unit.

@Bhaskar Can you please look into this?

Hi,
I believe you are using any i2c to scan.
are you able to control PWM if you manually set the address to 0x41 in anyi2c?
@ryan1 any thoughts?

Thanks

I will try that. I unfortunately sent 1 off for some mechanical design work. I do have a 16 channel I could hook to my 8 channel and try with though.
