Descriptions:
PWM output can set frequency and duty cycle respectively. Frequency is divided into four areas: automatic switching: 1.XXX (without decimal point): the smallest unit is 1Hz, and the value range is 1Hz~999Hz;The minimum unit of 2.X.XX (decimal point in 100 bits) is 0.01Khz, and the value range is 1.00Khz~9.99Khz; 3.XX.X (decimal point in ten places): the smallest unit is 0.1Khz; and the range is 10.0KHz~99.9KHz. 4.X.X.X (decimal point in ten bits and 100 bits): the smallest unit is 1Khz; and the range is 1KHz~150KHz.E.g. frequency display: 100 indicates PWM output 100Hz pulse;1.01 represents the pulse of PWM output 1.01K.54.1 represents the pulse of PWM output 54.1KHz.1.2.4 indicates the pulse of PWM output 124KHz.Duty cycle:0~100%;All settings are saved by power down. Parameter setting: Module has four independent keys, used to set the frequency and duty cycle, support short press (increase or decrease a unit) and long press (quickly increase or decrease), very simple, set the parameters automatically save, power loss is not lost. Scope of application: 1.is used as a square wave signal generator to generate square wave signals for experimental development. 2.is used to generate square wave signals that control motor drives. 3.generate adjustable pulse for MCU use; 4.generate adjustable pulses to control related circuits (PWM dimming and speed regulation applications).
Specification:
Working voltage: 3.3~30V Frequency range: 1Hz~150KHz Frequency accuracy: accuracy is about 2% in each range Signal load capability: output current can be around 5~30mA Output amplitude: PWM amplitude is equal to supply voltage Ambient temperature: -20~+70℃ Dimensions: 3.7x4.3x7.8cm/1.46x1.69x3.07inch Color: Black Quantity: 1 Pc
