1Hz-150 кГц экспериментальные легко Управление генератор сигналов PWM импульсный Регулируемая частота ЖК-дисплей квадратный рабочий цикл сигналов Портативный

Description:
100% brand new and high quality!
The module has four independent keys, used to set the frequency and duty cycle, support touch (increase or decrease a unit) and long press (fast increase or decrease), set the parameters automatically save, power down not lost.
LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle.
Wide frequency range, high .
Serial communication, TTL level.
The scope of application:
1. Used as a square wave signal generator, generate square wave signal for experimental development and use.
2. Used to generate a square wave signal that controls the motor driver.
3. Generate adjustable pulse for MCU use.
4. generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications).
5. serial control (single-chip TTL level communication).
