Giới thiệu 2 Channel PWM Generator Duty Cycle Pulse Frequency Module LED Digital Tube Board Module XY-PWM tại Lotte Market

Module description2 Channel PWM Generator Duty Cycle Pulse Frequency Module LED Digital Tube Board Module XY-PWM
Two independent PWM output, you can set the frequency, duty cycle;
Wide frequency range and high accuracy;
Serial communication
Two independent PWM output, you can set the frequency, duty cycle
XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz;
XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range 0.1KHz ~ 99.9KHz
X.X.X. (three decimal places): the smallest unit is 1Khz; value range 1KHz ~ 150KHz2 Channel PWM Generator Duty Cycle Pulse Frequency Module LED Digital Tube Board Module XY-PWM
Three frequency ranges share a duty cycle, all set parameters, power down save.

Parameter settings
Module has three buttons are: Set, Up, Down;
D1: PWM2 duty cycle; FR2: PWM2 frequency; dU2: duty cycle of PWM2), there will be a corresponding parameter before switching, by pressing the [Set] key, the four parameter values are switched (FR1: PWM1 frequency; Flashing prompts.
Press the Up, Down buttons to change the current parameter value (long press to fast or fast down).
Two PWM each preset three kinds of frequency value, in the frequency display interface, by pressing the 【SET】 key to switch, the three kinds of frequency duty cycle consistent. (XXX: range 1Hz ~ 999Hz; XX.X: range 0.1Khz ~ 99.9Khz; X.X.X .: range 1Khz ~ 150Khz,).2 Channel PWM Generator Duty Cycle Pulse Frequency Module LED Digital Tube Board Module XY-PWM
