Review: Awesome FAN PWM control - Did the demo to our VPs without any issues for controlling PWM of FAN, and hence the speed of FAN. Review: Output Current Capacity not specified - This is a really good device. I wish I knew the output current capacity so that I could protect it from shorts. ## Features - WIDE APPLICATION: The pwm pulse generator is used as generator to generate for experimental development and use to generate for controlling motor drivers - GENERATE ADJUSTABLE PULSES: This pulse frequency generator module generates adjustable pulses for MCU use and control related circuits (applications such as PWM dimming and speed regulation) - FEATURES: The rectangular generator has PWM output, this module can set the frequency and duty cycle separately, with wide frequency range and - LCD DISPLAY FUNCTION: The frequency and duty cycle of the LCD display are very clear. This pwm generator board can communicate with serial port. All setting parameters are saved after power off - SPECIFICATION: XXX (without decimal point): the smallest unit is 1Hz, in the range 1Hz ~ 999Hz, X.XX (one hundred decimal point) is minimum unit 0.01Khz, ranging 1.00Khz ~ 9.99Khz, XX.X (ten in decimal): minimum unit is 0.1kHz; range 10.0KHz ~ 99.9KHz, X.X.X (decimal in ten and one hundred): minimum unit is 1Khz; range 1KHz ~ 150KHz ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09KM5TL93 | | Accessory Connection Type | default | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #83,702 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #5 in Pulse Generators | | Customer Reviews | 4.4 4.4 out of 5 stars (30) | | Date First Available | October 28, 2021 | | Finish | Finish | | Handle Material | default | | Included Components | inc | | Installation Method | InstallationMethod | | Item Package Quantity | 1 | | Item Weight | 0.352 ounces | | Manufacturer | LiebeWH | | Material | Plastic | | Part Number | LiebeWHn4wbhgco5r2601 | | Power Source | PowerSource | | Product Dimensions | 3.15 x 1.57 x 0.79 inches | | Spout Height | 1 Centimeters | ## Images ![PWM Signal Generator Module Adjustable Frequency Duty Cycle Square Wave Rectangular Wave with LCD Display Board for Electronics Projects - Image 1](https://m.media-amazon.com/images/I/614InjINWRL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome FAN PWM control *by G***H on April 19, 2024* Did the demo to our VPs without any issues for controlling PWM of FAN, and hence the speed of FAN. ### ⭐⭐⭐⭐⭐ Output Current Capacity not specified *by A***S on January 5, 2024* This is a really good device. I wish I knew the output current capacity so that I could protect it from shorts. ### ⭐⭐⭐⭐ Good value....hard to find instructions. *by B***N on March 10, 2025* Works fine, but would have appreciated some instructions or a URL to go to. Very inexpensive though given what it does. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/481190202-pwm-signal-generator-module-adjustable-frequency-duty-cycle-square-wave](https://www.desertcart.ph/products/481190202-pwm-signal-generator-module-adjustable-frequency-duty-cycle-square-wave) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-06-28*
