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) Amazon.com . 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.
