1Hz/150kHz Signal Generator Module Xy-Lpwm

1Hz / 150kHz Square Wave Signal Generator Module Xy-lpwm

Adjustable Pulse Frequency Generator Experiment Development Board Motor Speed Control Driver Dimmer

A maximum of 30mA current can be drawn from the output. If it is connected to a circuit drawing high current, the product will be damaged. In an application drawing high current, a relay or transistor circuit must be added between the load and the module.

     Square wave generator module between 1-150khz. It has a wide frequency range and produces square waves with high accuracy. The frequency and duty parameters of the Pwm signal can be changed. There are 2 frequency adjustment buttons. There are also 2 duty adjustment buttons. In addition, the product settings can be made over ttl uart.

     A short press increases and decreases the parameter. A long press increases and decreases at high speed. The settings are saved automatically. The signal level varies depending on the supply voltage.

1) Setting 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) Setting the PWM Duty     

•   DXXX: set the PWM duty cycle to XXX; (001 ~ 100)
•   Such as D050, set the PWM duty cycle is 50%

3) Reading the Parameters

•   Send a "read" string to read the set parameters.
•   Set successfully return: Down
