XY-LPWM 1Hz-150Khz Signal Generator PWM Board Module Pulse Frequency Duty Cycle Adjustable Module LCD Display 3.3V-30V For more details, please see the link picture, thank you Highlights 1 LCD display frequency and duty cycle, very clear, PWM output can be set separately frequency and duty cycle; 2. Wide frequency range, high precision; 3. It can use serial communication Description PWM output, you can set the frequency, duty cycle; Frequency is divided into four ranges, automatic switching: 1. XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz; 2. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz; 3. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz 4. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz e.g. frequency display: 100 indicates PWM output 100Hz pulse; 1.01 indicates PWM output 1.01K pulse; 54.1 indicates that the PWM output has a pulse of 54.1 kHz; 1.2.4 indicates that the PWM output is 124 kHz pulse; Duty cycle range: 0 ~ 100%; All set parameters, power down save. Parameter settings The module has four independent keys, used to set the frequency and duty cycle, support short press (increase or decrease a unit) and long press (fast increase or decrease), very simple, set the parameters automatically save, power failure Lost. Module parameters 1. Working voltage: 3.3 ~ 30V; 2. Frequency range: 1Hz ~ 150KHz; 3. Frequency accuracy: the accuracy in each range is about 2%; 4. Signal load capacity: the output current can be about 5 ~ 30ma; 5. Output amplitude: PWM amplitude equal to the supply voltage; 6. Ambient temperature: -20 ~ +70 ℃. 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 related circuit (PWM dimming speed and other applications) For more details, please see the link picture, thank you Package Included: 1pcs * XY-LPWM 1Hz-150Khz Signal Generator PWM Board Module Before purchase: 1.
