1.Operating voltage3.3~30V;
2. Frequency range1Hz~150KHz;
3. Frequency accuracy:In each range of accuracy is about 2%
4. Signal load capacity:Output current can be around 5~30ma
5. Output amplitude: PWM amplitude and supply voltage equal
6. Ambient temperature:-20~+ Parameter:
Has 8 independent keys,used to set the frequency and duty ratio,support short press (increase or decrease a unit) and long press (fast increase or decrease),very simple,set the parameters automatically save,power loss.
3-Way duty ratio button can be pressed at the same time,real-time adjustment, liquid crystal display is the last pressed button duty ratio,real-time is very strong,can be used as a simple several road duty ratio scan.
Applications:
1.Used as square wave signal generator to generate square wave signal for experiment development and use
2.Used to generate a square wave signal to control the motor driver;
3.Generating adjustable pulses for MCU use;
4.Generate adjustable pulse, control related circuit (PWM dimming speed and other applications).
UART Serial command:

1.set the frequency of the PWM
"F101": Set frequency of 101 HZ (001~999)
"F1.05": Set frequency of 1.05 KHZ(1.00~9.99)
"F10.5": Set frequency of 10.5KHZ(10.0~99.9)
"F1.0.5":Set frequency of 105KHZ(1.0.0~1.5.0)
2.set the duty ratio of PWM
"DX:YYY": Set PWM duty ratio x: (1~3) PWM serial number,YYY: (000~100) duty ratio;
For example d1:050,set 1th PWM duty ratio to 50%

Molto sensibili alle cariche elettrostatiche durante la manipolazione ed anche la saldatura. Ne ho bruciati diversi , occorre quindi mettere a terra sia il proprio corpo che il saldatore.

An den 3 Kanälen wird die gepulste Eingangsspannung ausgegeben.Allerdings über einen 1 kOhm Widerstand - die 0 V werden über einenTransistor oder FET geschalten.Leider keine push-pull Endstufe.Sonst durchaus sehr brauchbar um diesen Preis!
