## 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: 2x Signal Generator
