Specification:
Working voltage: 3.3-30V;
Frequency range: 1Hz-150KHz;
Frequency accuracy: The accuracy of each range is about 2%;
Signal carrying capacity: The output current can be around 5-30ma;
Output amplitude: PWM amplitude is equal to the power supply voltage;
Environmental temperature: -20-+70 ℃.
Size: 52 * 32mm/2.04 * 1.25inch

LCD display frequency and duty cycle, clear at a glance, PWM output can be set separately for frequency and duty cycle;
Wide frequency range and high accuracy;
Can use serial communication
PWM output, frequency and duty cycle can be set;
The frequency is divided into four ranges and automatically switches:
1. XXX (without Decimal separator): the minimum unit is 1Hz, and the value range is 1Hz-999Hz;
2. X.XX (hundred Decimal separator) The minimum unit is 0.01Khz, and the range is 1.00Khz-9.99Khz;
3. XX. X (ten Decimal separator): the minimum unit is 0.1Khz; Value range: 10.0KHz-99.9KHz
4. XXX (Decimal separator of tens and hundreds): the minimum unit is 1 Khz; Value range: 1KHz-150KHz
For example, frequency display: 100 represents PWM output of 100Hz pulse;
1.01 represents PWM output of 1.01K pulses;
54.1 indicates that the PWM output has a pulse of 54.1kHz;
1.2.4 indicates that the PWM output is a 124kHz pulse;
Duty cycle range: 0-100%;
All set parameters, save after power down.
Applicable scope
1. Used as a square wave signal generator to generate square wave signals for experimental development;
2. Used to generate square wave signals for controlling motor drivers;
3. Generate adjustable pulses for MCU use;
4. Generate adjustable pulses and control related circuits (applications such as PWM dimming speed)
Parameter settings
The module has four independent buttons for setting frequency and duty cycle, and supports short pressing (increasing or decreasing by one unit) and long pressing (quickly increasing or decreasing). It is very simple, and the setting parameters are automatically saved, resulting in power loss.
Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
