I have a servo with an operating voltage of 4.8V. I want to drive the servo from a MCU running on 3.3V. I haven't tried it yet, but was wondering if I needed to drive the signal line to 4.8V using a MOSFET or NPN transistor. Is it possible to drive a 4.8V servo using 3.3V signal? Will the performance be impacted?
If I need to drive it with 4.8V how should I connect it? The gate obviously goes to the signal (with the necessary resistance) but how do I connect the servo's signal line? Should I connect the signal line to 4.8V and the ground to the drain? I'm guessing this wouldn't work. Is this even possible?
