It features adjustable pulse frequency and duty cycle (0-100%), automatic parameter memory retention, and TTL-level serial communication, making it an essential tool for precise waveform generation in professional and hobbyist electronics projects. ## 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 one unit by one 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~150kHz e.g. Frequency displays 100 represents 100Hz; displays 1.01 represents 1.01kHz; displays 54.1 represents 54.1kHz; displays 1.2.4 represents 124kHz Package Included: 1x Signal Generator Review: Drok signal generator - Arrived the next day, worked as it was intended.good buy for the price. I don't know how long it will last under more use. Review: It works as advertised - Excellent signal generator!!! It fulfill my expectations,100% recommend it. Shipment also fast and without any issues ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07KVYQ78K | | Brand Name | DROK | | Customer Reviews | 4.4 out of 5 stars 318 Reviews | | Manufacturer | DROK | | Material Type | Electronic Components | | Maximum Supply Voltage | 30 Volts | | Maximum supply voltage | 30 Volts | | Minimum Supply Voltage | 3.3 Volts (DC) | | Minimum supply voltage | 3.3 Volts (DC) | | Model | 200382AFA | | Mounting Type | Freestanding | | Mounting type | Freestanding | | Number of Channels | 1 | | Operating Temperature | 70 Degrees Celsius | | Output Power | 900 Milliwatts | | Package Type Name | Single Unit | | Part Number | 200382AFA | | Specification Met | CSA | | Supply Current | 15 Milliamps | | Voltage | 30 Volts | ## Product Details - **Voltage:** 3E+1 Volts (DC) - **Manufacturer:** DROK - **Maximum supply voltage:** 3E+1 Volts - **Minimum supply voltage:** 3.3 Volts (DC) - **Mounting type:** Freestanding ## Images ![DROK 3.3-30V Signal Generator, DC Function Generator 1 Channel 5-30mA PWM Pulse Frequency Duty Cycle Rectangular Wave Square Wave - Image 1](https://m.media-amazon.com/images/I/61kM9aOHkjL.jpg) ![DROK 3.3-30V Signal Generator, DC Function Generator 1 Channel 5-30mA PWM Pulse Frequency Duty Cycle Rectangular Wave Square Wave - Image 2](https://m.media-amazon.com/images/I/71EhDITiMxL.jpg) ![DROK 3.3-30V Signal Generator, DC Function Generator 1 Channel 5-30mA PWM Pulse Frequency Duty Cycle Rectangular Wave Square Wave - Image 3](https://m.media-amazon.com/images/I/61Fsa9RlhGL.jpg) ![DROK 3.3-30V Signal Generator, DC Function Generator 1 Channel 5-30mA PWM Pulse Frequency Duty Cycle Rectangular Wave Square Wave - Image 4](https://m.media-amazon.com/images/I/71ezbEDP5iL.jpg) ![DROK 3.3-30V Signal Generator, DC Function Generator 1 Channel 5-30mA PWM Pulse Frequency Duty Cycle Rectangular Wave Square Wave - Image 5](https://m.media-amazon.com/images/I/71Ze41zsK7L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Drok signal generator *by S***Y on 8 July 2026* Arrived the next day, worked as it was intended.good buy for the price.
