Not sure if this is the right place for this question or if it should be in general electronics, if anyone thinks I should move it I'll be more than happy to oblige.
I have a number of stepper motors and drivers which I'll be controlling using an Arduino Mega, which obviously outputs a 5V signal from its PWM pins. My drivers, however, require a 28V signal to their inputs (i.e. pulse and direction control inputs, the actual power comes from a 48V power supply plugged into the mains).
My question is, is there a simple circuit to step up the 5V signal from the Arduino into a 28V signal that the drivers will recognise?
Thanks in advance for your help
