Specification Brand : Generic BulletPoint : DC 5-30V Micro USB 5V Power Independent PWM Signal Generator 2 Channel Dual Way Digital LED Duty Cycle Pulse Frequency Board ItemName : Generic DC 5-30V Micro USB 5V Power Independent PWM Signal Generator 2 Channel Dual Way Digital LED Duty Cycle Pulse Frequency Board ItemTypeKeyword : function-generators Manufacturer : Generic PartNumber : TJUJ_YUD_13885 ProductDescription : Highlights: Two independent PWM generators can set the frequency, duty cycle; The wide frequency range, high accuracy; Can serial communication. First, the module description: Frequency is divided into three ranges: XXX (no decimal point): the smallest unit is 1Hz, the range 1Hz ~ 999Hz; XX.X (decimal point in ten): The minimum unit is 0.1Khz; the range of 0.1KHz ~ 99.9KHz X.X.X. (there are three decimal point): the smallest unit is 1Khz; the range 1KHz ~ 150KHz Frequency display example: "100" indicates that the PWM output pulse of 100Hz; "54.1" indicates that the PWM output pulse of 54.1KHz; "1.2.4." Indicates that the PWM pulse output 124KHz Duty Cycle in the range: 0 to 100; Three frequencies duty cycle is the same, all the parameters non-volatile. Second, the module parameters: Working voltage: 5--30V, support micro USB 5.0V power supply; Frequency range: 1Hz ~ 150KHz; The frequency accuracy: ± 2%; Output Current: <30mA; Output amplitude: Default 5Vp-p (settable); Operating temperature range: -30 ~ + 70 °. Third, the parameter settings: Module has three buttons [Set], [Up], [Down]; Press [Set] key to switch the display four parameters (FR1: PWM1 frequency; dU1: PWM1 duty cycle; FR2: frequency of PWM2; dU2: PWM2 duty cycle), before the handover parameters, there will be corresponding parameter name flash. Press [Up], [Down] keys to modify the current parameter value (long press can quickly add or subtract fast). Two PWM each have three preset frequency, the frequency display interface, long press [SET] key to switch between three types of frequencies, three kinds of frequency duty cycle is the same value. (XXX: range 1Hz ~ 999Hz; XX.X: range 0.1Khz ~ 99.9Khz; X.X.X .: range 1Khz ~ 150Khz,). Fourth, ProductSiteLaunchDate : 2024-06-07T15:32:29.899Z
