Hi, it looks like the Pi is setup, maybe you are using the wrong address for the pca9685 driver in reef-pi.

After you change it in reef-pi go to the admin tab and press the reload button.

let us know if your issue is resolved. we need some more details to pin down the problem. your prompt looks like the ic is detected. what address you are using in the driver configuration and check if you are seeing any error in the logs.
update to 4.3 if possible
