I am using a 3.3V, 3.6A Step-Down Voltage Regulator, D36V28F3, to power several esp32-based sensors on my boat (12vdc). Should I also use bypass capacitors near the microcontroller?

Hello, Mo.
It depends on the details of your system, but in general, if you are powering both your sensors and your microcontroller from the D36V28F3 regulator, there are several factors that might make it a good idea to add bypass capacitors:
But it might also be unnecessary. The best way to get a better idea about that would be to monitor your system with a scope.
