Hukai PWM Pulse Frequency Duty Cycle Adjustable Module Signal Generator LCD Display

100% brand new and high quality Features: LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle. Wide frequency range, high precision. Serial communication, TTL level. 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. 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). Specification: Working voltage: 3.3 ~ 30V Frequency range: 1Hz ~ 150KHz Frequency accuracy: the accuracy in each range is about 2% Signal load capacity: the output current can be about 5 ~ 30ma Output amplitude: PWM amplitude equal to the supply voltage Ambient temperature: -20 ~ +70 ? Dimensions: 52x32mm/2.05x1.26inch Main color: Green&black Quantity: 1 Pc Note: 1.Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
