Adjustable PWM Pulse Frequency Duty Cycle Square Wave Signal Generator Module

Description: Product Description Adjustable PWM Pulse Frequency Duty Cycle Square Wave Signal Generator Module Description: PWM output, you can set the frequency, duty cycle; Frequency is divided into four ranges, automatic switching: 1. XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz;2. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz;3. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz4. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz e.g. 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. Features: 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 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. Applications: 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: 8Stop bit: 1Check digit: noneFlow control: none1. 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)2. 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%3. Read the setting parametersSend a "read" string to read the set parametersSet successfully return: DOWNSetup failed to return: FALL Specifications: Working voltage: 3.3 ~ 30VFrequency range: 1Hz ~ 150KHzFrequency accuracy: the accuracy in each range is about 2%Signal load capacity: the output current can be about 5 ~ 30mAOutput amplitude: PWM amplitude equal to the supply voltageAmbient temperature: -20 ~ +70 ℃Size: 5.1x3.2cm/2.01x1.26"Quantity: 1 Pc Note: 1.
