5V Stepper Motor Pulse Generator 0–20KHz Adjustable Speed Controller
5V Stepper Motor Speed Controller — Adjustable Pulse Generator 0–20KHz
Take precise command of your stepper motor projects with this compact, easy-to-use 5V Output Pulse Generator. Designed for hobbyists, engineers, and makers alike, this adjustable pulse regulator lets you dial in the exact output frequency your stepping motor needs — anywhere from 0 to 20KHz — all from a convenient, portable form factor.
Key Features
- Wide Frequency Range: Continuously adjustable pulse output from 0 to 20,000 Hz (20KHz) for precise stepper motor speed regulation.
- Clean 5V Output: Delivers a stable 5V regulated output signal at up to 10mA — compatible with most stepper motor driver boards.
- Portable & Compact: Small 58mm × 56mm × 44mm form factor makes it ideal for benchtop testing, prototyping, or field use.
- Simple 9V Battery Power: Runs on a standard 9V battery (not included) — no mains power or complex wiring required.
- No Wireless Interference: Fully wired operation with no wireless components for a clean, noise-free signal environment.
- Low-Voltage Safe: Operates below 50V AC / 75V DC, meeting EU LVD low-voltage safety guidelines.

Frequently Asked Questions
Q: What type of stepper motor drivers is this pulse generator compatible with?
A: This 5V output pulse generator is compatible with most common stepper motor driver boards that accept a standard 5V TTL/logic-level pulse signal, such as the A4988, DRV8825, and similar step/direction driver modules. Always verify your driver's input signal voltage requirements before connecting.
Q: Is a battery included with the stepper motor speed controller?
A: No, a 9V battery is not included with the pulse generator. You will need to supply your own standard 9V battery to power the unit.
Q: Can I use this pulse generator for applications other than stepper motors?
A: Yes — while this device is optimised for stepper motor speed regulation, its 0–20KHz adjustable 5V pulse output can also be useful for other electronics prototyping tasks such as testing pulse-triggered circuits, timing applications, and similar projects that require a variable-frequency square wave signal.
