Description:

1Hz-150KHz PWM Pulse Frequency Duty Cycle Adjustable Module Signal Generator 

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 C.
Module description
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).
Size:7.8x4.2x2.6cm/3.07x1.65x1.02inch
Note:
Please allow 1-3mm error due to manual measurement.pls make sure you do not mind before you bid.

Commetns green-k.ru :
Everyone is happy except the packaging-was wrapped simply in polyethylene. It was less than a month in the cbd. Not included yet, but with the appearance of decency.

The package came quickly, to stavropol for two weeks. the package is weak, in a double package, in the work has not yet checked. Seller respect, i recommend.

I order a second time, colleagues now.

Great. I use for washing fuel injectors

The transistor is weak, it is better to change.

The signal generator fully corresponds to the description. The frequency and skepticism keeps in accordance with the indicator quite accurately. The parcel reached less than a month before the samara region. I advise you to buy.

Quality and good thing. Assembled and works great!!! Shipping fast! Seller-thank you!!!

Thank you

Thanks to the order received all intact and safe. Thank you for the fast delivery.

Delivery by e-packet to saransk 10 days. Everything is safe and sound.

Ok!

Good device. I like it.

Delivery is fast. The product corresponds to the description. I recommend.

Thank you.

The screen surface is damaged. Although packed was good

perfect machine

OK

Thank you! I liked the goods, it works properly.

Delivery is fast. Generator ok. Thanks to the seller.
