XY-LPWM Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module LCD Display 1Hz- 150Khz 3.3V-30V PWM Board Module

1. Working voltage: 3.3 ~ 30V2. Frequency range: 1Hz ~ 150KHz3. Frequency accuracy: the accuracy in each range is about 2%4. Signal load capacity: the output current can be about 5 ~ 30ma5. Output amplitude: PWM amplitude equal to the supply voltage6. Ambient temperature: -20 ~ +70 °

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 ~ 99.9KHz4. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHze.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.   Module parameters:1.
