4-in-1 esc with Arduino
I'm working on a project where I have to spin 4 motors at certain RPMs and I am thinking about using a 4-in-1 esc as its cheaper currently, I tried searching up what the input signal would be for the esc but couldn't figure it out, can I power the esc without lipo cells? I have a variable power supply, can they work too? (the 4 motors do not need to spin in different speeds) thank you
Most ESCs need 5v PWM (RC format). You want LIPO cells or you may have problems under load.
You want a board that has 5V native to generate RC PWM like this:
