4>.Keep press button ‘ON/OFF’ for 5 second to switch to Normal mode and Precise mode.
5.Button description
1>.Long press means need keep press for more than 3second.
2>.Short press button ‘ON/OFF’ to enabled/disabled PWM output.
3>.Keep press button ‘ON/OFF’ for 2 second to lock parameters and display lock symbol at the same time then these parameters can not be set and avoid misoperation.Press 2 second again to release lock function.
4>.Keep press button ‘ON/OFF’ for 5 second to switch to Normal mode and Precise mode.
5>.Short press button ‘SET’ to switch display set parameters for frequency and duty cycle and amplitude.Then press button ‘UP’ and ‘DOWN’ to set parameter value.
6>.Keep press button ‘SET’ for 2 second to set system parameters for ddn/dup/Fdn/FUP/Adn/AUP/dEF.Then press button ‘UP’ and ‘DOWN’ to set system parameter value.
6.Use steps
1>.Connect to power supply.
2>.Set Normal mode and Precise mode.
3>.Set parameters for frequency and duty cycle and amplitude.
4>.Set system parameters for ddn/dup/Fdn/FUP/Adn/AUP/dEF if need set.
5>.Keep press ‘ON/OFF’ for 2second to lock set parameters.
6>.Test.
7>.Press button ‘ON/OFF’ to turn on or off PWM output.
8>.Remove power and connect load to use module.
7.Application
1>.Square wave signal generator, generating square wave signal for experimental development
2>.Used to generate a square wave signal that controls the motor driver
3>.Generate adjustable pulses for use by the MCU
4>.Dimmer
5>.Speed governor
8.Note
1>.It’s 1-channel PWM output signals.
2>.Its maximum output current is 30mA.Therefore it cannot directly drive high-power devices.
