2 Channel Dual Way Independent PWM Generator Digital LED Duty Cycle Pulse Frequency

Description

2 Channel Dual Way Independent PWM Generator Digital LED Duty Cycle Pulse Frequency

Board Module 5-30V/Micro Usb 5V Power
Module description
• Two independent PWM output, you can set the frequency, duty cycle;
• Wide frequency range and high accuracy;
• Serial communication
• Two independent PWM output, you can set the frequency, duty cycle
• XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz;
• XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range 0.1KHz ~ 99.9KHz
• X.X.X. (three decimal places): the smallest unit is 1Khz; value range 1KHz ~ 150KHz
• Three frequency ranges share a duty cycle, all set parameters, power down save.

Parameter settings
• Module has three buttons are: Set, Up, Down;
• D1: PWM2 duty cycle; FR2: PWM2 frequency; dU2: duty cycle of PWM2), there will be a corresponding parameter before switching, by pressing the [Set] key, the four parameter values are switched (FR1: PWM1 frequency; Flashing prompts.
• Press the Up, Down buttons to change the current parameter value (long press to fast or fast down).
• Two PWM each preset three kinds of frequency value, in the frequency display interface, by pressing the ?SET? key to switch, the three kinds of frequency duty cycle consistent. (XXX: range 1Hz ~ 999Hz; XX.X: range 0.1Khz ~ 99.9Khz; X.X.X .: range 1Khz ~ 150Khz,).

Module parameters:
• Operating voltage: 5 – 30V support micro USB 5.0V power supply;
• Frequency range: 1Hz ~ 150KHz;
• Frequency accuracy: the accuracy in each range is about 2%;
• Signal load capacity: the output current can be 8 – 30ma or so;
• Output amplitude: default 5V V-pp (can be changed by external power supply);
• Ambient temperature: -30 ~ +70 ?.

Applicable scope
• Used as a square wave signal generator, generate square wave signal for experimental development and use;
• For generating a square wave signal for driving the stepper motor driver;
• Generate adjustable pulse for MCU use;
• Produce adjustable pulse, control related circuit (PWM dimming speed and other applications)

Package Included:
• 1 x 2 way Independent PWM Generator
