Featuring an intuitive LCD display, auto-saving settings, and versatile PWM output, it’s engineered for professionals seeking reliable, adjustable square wave and pulse signals for experimental development, motor control, and MCU applications. ## Description Parameter: 1. Working voltage: DC 3.3v~30v 2. Frequency range: 1Hz~150kHz (divided into 4 ranges); 3. Frequency precision: 2% of each range; 4. Signal load capacity: output current is about 5-30mA; 5. Output Amplitude: PWM amplitude equal to the input voltage value 6. Environment Temperature Range: -20~+70℃ 7. Duty cycle range: 0-100%.Application: 1. As square wave signal generator for experimental development; 2. As square wave signal generator for motor driver; 3. As adjustable pulse generator for MCU; 4. As pulse generator, control related circuits (PWM dimming, speed regulating).Setting Parameters: There are 4 independent buttons on the module for setting the frequency value and the duty cycle value. Supports short press (increase or decrease 1 unit by 1 unit) and long press (fast increase or decrease). All setting parameters will be saved when powered off to achieve data guaranteed.Frequency Display Instruction: The frequency is divided into 4 ranges and switched automatically. 1. XXX (without decimal point): minimum unit is 1Hz, value range is 1Hz~999Hz. 2. X.XX (the decimal point is in the hundred digit): minimum unit is 0.01kHz, value range is 1.00kHz~9.99kHz. 3. XX.X (the decimal point is in the ten digit): minimum unit is 0.1kHz; value range is 10.0kHz~99.9kHz. 4. X.X.X (full decimal point): the minimum unit is 1kHz; the value range is 1kHz~150kHze.g. Frequency displays 100 represents 100Hz; displays 1.01 represents 1.01kHz; displays 54.1 represents 54.1kHz; displays 1.2.4 represents 124kHzPackage Included: 1x Signal Generator ## Features - PARAMETER ---- operating voltage range DC 3.3v~30v; frequency range 1Hz-150kHz; output current 5-30mA; duty cycle range 0-100%. - APPLICATION ---- as square wave signal generator for experimental development; as square wave signal generator for motor driver; as adjustable pulse generator for MCU; as pulse generator, control related circuits (PWM dimming, speed regulating). - SERIAL COMMUNICATION ---- support serial communication, TTL level. - DATA AUTO STORAGE ---- all parameters will be saved automatically after setting and therefore won't lose when power off. - OTHER FEATURES ---- with LCD display to display frequency and duty cycle value; with case; PWM output, can set frequency and duty cycle separately by buttons; frequency value is divided into 4 range and switched automatically, with high precision. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07KVYQ78K | | Best Sellers Rank | #25,680 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #4 in Function Generators | | Brand | DROK | | Brand Name | DROK | | Customer Reviews | 4.5 out of 5 stars 320 Reviews | | Manufacturer | DROK | | Material Type | Plastic, Lcd | | Maximum Supply Voltage | 30 Volts (DC) | | Minimum Supply Voltage | 3.3 Volts | | Model | 200382AFA | | Mounting Type | Surface Mount | | Number of Channels | 1 | | Operating Temperature | 70 Degrees Celsius | | Output Power | 900 Milliwatts | | Part Number | 200382AFA | | Voltage | 30 Volts | ## Product Details - **Manufacturer:** DROK - **Maximum Supply Voltage:** 30 Volts (DC) - **Minimum Supply Voltage:** 3.3 Volts - **Mounting Type:** Surface Mount - **Voltage:** 30 Volts ## Images ![DROK 5-30mA Signal Generator - Image 1](https://m.media-amazon.com/images/I/61kM9aOHkjL.jpg) ![DROK 5-30mA Signal Generator - Image 2](https://m.media-amazon.com/images/I/71EhDITiMxL.jpg) ![DROK 5-30mA Signal Generator - Image 3](https://m.media-amazon.com/images/I/61Fsa9RlhGL.jpg) ![DROK 5-30mA Signal Generator - Image 4](https://m.media-amazon.com/images/I/71ezbEDP5iL.jpg) ![DROK 5-30mA Signal Generator - Image 5](https://m.media-amazon.com/images/I/71Ze41zsK7L.jpg) ## Available Options This product comes in different **Number Of Items** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by K***. on April 23, 2026* ### ⭐⭐⭐⭐⭐ Review *by R***H on November 23, 2025* ### ⭐⭐⭐⭐ Review *by M***O on March 31, 2024* ## Frequently Bought Together - DROK Signal Generator, DC 3.3-30V Function Generator 5-30mA LCD Display PWM Pulse Frequency Duty Cycle Rectangular Wave Square Wave Signal Generator - DROK Frequency Generator, DC 3.3V-30V 5-30mA 1Hz-150kHz Adjustable Output PWM Pulse Duty Cycle Square Wave Function Signal Generator Module - HiLetgo 2pcs 3 Channel PWM Pulse Generator Signal Generator Module Adjustable Frequency Square Wave Rectangular Wave Signal Generator Duty Cycle with LCD Display 1Hz-150Khz --- ## 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.co.uk/products/97097141-drok-5-30ma-signal-generator](https://www.desertcart.co.uk/products/97097141-drok-5-30ma-signal-generator) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-15*
