Why we recommend it
These LM2596 modules are the easy way to give servos a clean, separate power rail. The on-board LED voltmeter is the killer feature: you can read and set the output to exactly 5–6V before connecting anything, so you never feed your servos too much. Wire a 9–12V adapter or battery into the input and the regulated output into the servo driver’s power terminal — keeping those current spikes off your Arduino. A five-pack means spares for every project.
