No way to impiment?

I'm sorry if I'm missing something, but there's no code or programs here it's just images of hardware wiring. How would I go about coding the ESP32 or acquiring the Android app?

Also, why do the 3 and 4 channel examples shown each have 2 and 3 outputs respectively? If using a PWM controller like the one linked at bottom do I just wire the +V and GND directly into the inputs of a MOSFET board?

So those boards are just some of the examples used in different machines.

Those specific 400w mosfets, have their positive plane connected. If you screw into the pos, the other side is on - connected or not.

So the power switch is positive, and pos lines run straight to the motor. The neg line goes from the mosfet to the motor. This is a board specific issue. There are many options.

I usually share a ground for all the mosfets.

I think I might understand better now about the inputs not matching. One of the uses a GX16 aviation connector with a 6 core wire terminal.

The 4 channel one of the right has DC barrel jack outputs underneath each mosfet. Hope I helped ;)
