Product Description

*With LCD LCD display frequency and duty cycle, very clear, PWM output, can set frequency and duty cycle separately
*Wide frequency range and high precision;
*Serial communication
*PWM output, can set the frequency and duty cycle separately
*The frequency is divided into four ranges and automatically switched:
1.XXX (no decimal point): The minimum unit is 1 Hz, and the value ranges from 1 Hz to 999 Hz.
2.X.XX (the decimal point is in the hundredth place) The minimum unit is 0.01Khz, and the value range is 1.00Khz~9.99Khz;
3.XX.X (decimal point is ten): the minimum unit is 0.1Khz; the value range is 10.0KHz~99.9KHz
4.X.X.X (decimal point in ten and hundred): the minimum unit is 1Khz; the value range is 1KHz~150KHz
E.g. Frequency display: 100 means PWM output 100Hz pulse;
1.01 indicates that the PWM outputs a pulse of 1.01K;
54.1 indicates that the PWM outputs a pulse of 54.1 kHz;
1.2.4 indicates that the PWM output is a pulse of 124KHz;
*The duty ratio ranges from 0 to 100%;
*All setting parameters, save power
*The module has 4 separated buttons, which are used to set the frequency and duty ratio. It supports short press (increase or decrease one unit) and long press (fast increase or decrease). It is very simple, and the parameters are automatically saved after setting. Not lose if power off

*Frequency range: 1Hz~150KHz
*Frequency accuracy: the accuracy in each range is about 2%
*Signal load capacity: The output current can be around 5~30ma
*Output amplitude: The PWM amplitude is equal to the power supply voltage
*Ambient temperature: -20~+70degree Celsius
*Scope of application:
1. Used as a square wave signal generator, generate a square wave signal for experimental development
2. Used to generate a square wave signal that controls the motor driver
3. Generate adjustable pulses for MCU
4. Generate adjustable pulses, control related circuits (PWM dimming, speed control and other applications)


Notes: The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.
