The adafruit_pca9685.motor.DCMotor class AND adafruit_pca9685stepper.Steppers() both show 0x60 as the default address. I think they both should be 0x40 since the Adafruit board has a default address of 0x40.
If you agree i can make this change.

Thanks for finding this @notthatbrad and @mrmcwethy! Would either of you be willing to submit a pull request to fix it?

I'm pretty new to github, so not sure if I would be the best to do that, but I'll be happy to do anything I can. I can say that updating the motor.py file locally to 0x40 on my pc has corrected the error.
@mrmcwethy it failed looking for one on 0x40? Did you have a PCA9685 connected?

@notthatbrad I don't have that board, so I did expect to get that error. It just means i didn't make a big mistake and add syntax errors and i proved that the default address is now 0x40. I am going to release my changes.

Groovy, that's why I was wondering. I had accidentally hooked mine up backwards earlier, and I got the error as well on code that I knew should be working.
Let me know when the changes are made, and I'll download the new version to test as soon as I can.

Fixed in the driver commit: adafruit/Adafruit_CircuitPython_PCA9685@c227c10
I'll leave this open until we release a new version.

FYI, 0x60 makes sense for motors and stepper motors because its the default address of the motor featherwing. The servowing is 0x40 by default. I'm fixing this up with my rework of the PCA9685 drivers.

So it is (I just got the motor featherwing, and am testing it now)....but if I recall correctly, when using the PCA9685 breakout, the address is is 0x40, and the learn site has the featherwing documented as 0x40.

This could be really confusing for people looking for the driver for the PCA9685 breakout

Yup, I'll be refining it shortly.
