We are using the PCA9685 16 Channel in a High Vibration environment. Do you see any weird side effects with epoxying around the MOSFETS to help hold them in place? They seem to cause us the most issues on devices that encounter severe and sudden vibration.
are you epoxying just the FETS or all electronics parts ?
Although Epoxy shouldn’t create any problem.
Just the FETS as they tend to bend when a sever vibration occurs.
can you share a picture of the board.
