Servo controllers: shield vs. PCA9685

I’m curious if there are any technical differences between the servo shield and the PCA9685, found many places online, such as (chosen for no particular reason) https://www.amazon.com/HiLetgo-PCA9685-Channel-12-Bit-Arduino/dp/B01D1D0CX2 . The shield fits nicely onto the OpenMV board profile, and that is not an advantage to go underappreciated, but I’m curious if there are other technical differences that I am not savvy enough to appreciate (short of the different number of supported servos of course).

Thanks.

No, not really. We just used the circuit on a shield for the camera. That’s all.

Thanks. That’s what I expected.
