## Overview

The DROK Signal Generator is a compact, high-precision function generator operating from 3.3V to 30V, capable of producing square wave signals from 1Hz to 150kHz with a fully adjustable 0-100% duty cycle. Featuring an intuitive LCD display, TTL serial communication, and automatic parameter memory, it’s engineered for professionals seeking reliable PWM pulse control for motor drivers, MCU projects, and experimental development.

## 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

Review: Works great! - This is an easy, cheap way to generate test frequencies. I'm using it to dial in audio frequencies for chiptune projects. It's very simple to use the included serial functionality. A few jumpers to a Raspberry Pi or TTL serial adapter and you're good to go.
Review: Good product - Easy to use and works as advertised. Just purchased a second one for another project.
