Signal Generator PWM Pulsfrequenz Einstellbares Modul LCD Display 1Hz-150Khz 3,3V-30V PWM Board Modul

LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle

Wide frequency range, high precision

Serial communication, TTL level

PWM output, you can set the frequency, duty cycle

Frequency is divided into four ranges, automatic switching

XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz

X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz

XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz

X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz

Frequency display:

100 indicates PWM output 100Hz pulse

1.01 indicates PWM output 1.01K pulse

54.1 indicates that the PWM output has a pulse of 54.1 kHz

1.2.4 indicates that the PWM output is 124 kHz pulse

Duty cycle range: 0 ~ 100%

All set parameters, power-down automatically saved

Parameter settings

The module has four independent keys, used to set the frequency and duty cycle, support touch (increase or decrease a unit) and long press (fast increase or decrease), set the parameters automatically save, power down Not lost

Module parameters

Working voltage: 3.3 ~ 30V

Frequency range: 1Hz ~ 150KHz

Frequency accuracy: the accuracy in each range is about 2%

Signal load capacity: the output current can be about 5 ~ 30ma

Output amplitude: PWM amplitude equal to the supply voltage

Ambient temperature: -20 ~ +70 ºC

The scope of application

Used as a square wave signal generator, generate square wave signal for experimental development and use

Used to generate a square wave signal that controls the motor driver

Generate adjustable pulse for MCU use

Generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications)

Serial control (single-chip TTL level communication)

Communication standard:

9600 bps Data bits: 8

Stop bit: 1

Check digit: None

Flow control: None

Set the frequency of the PWM

"F101": Set the frequency to 101 HZ (001 to 999)

"F1.05": set the frequency of 1.05 KHZ (1.00 ~ 9.99)

"F10.5": Set the frequency to 10.5KHZ (10.0 ~ 99.9)

"F1.0.5": set the frequency of 105KHZ (1.0.0 ~ 1.5.0)

Set the PWM duty cycle

"DXXX": set the PWM duty cycle to XXX; (001 ~ 100)

Such as D050, set the PWM duty cycle is 50%

Read the set parameters

Send a "read" string to read the set parameters

Set successfully return: DOWN

Setup failed to return: FALL
