DROK Signal Generator, DROK DC 3.3-30V Function Generator 5-30mA LCD Display PWM Pulse Frequency Duty Cycle Rectangular Wave Square Wave Signal Generator

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 ...
