XY-PWM Frequency generator LCD 0-150kHz 3.3V-30V

Product detailed description

XY-PWM Frequency Generator LCD 0-150kHz 3.3V-30V

PWM output. You can set the frequency and duty cycle. Large frequency range, high accuracy. Serial driving! Feedback.

Frequency is divided into four bands, automatic switching:

1. XXX (no decimal point): smallest unit is 1Hz, range 1Hz - 999Hz;
2. X.XX (decimal point in hundreds) smallest unit is 1.00 KHz, range 1.00 KHz - 9.99 KHz;
3. XX.X (decimal point in tens): smallest unit is 10.0Khz; range 10.0KHz - 99.9KHz
4. X.X.X (three decimal points): smallest unit is 1Khz; range 1KHz - 150KHz

Examples of displayed frequency:

1. "100" indicates that the PWM output pulse is 100Hz
2. "1.01" indicates that the PWM output pulse is 1.01K
3. "54.1" indicates that the PWM output pulse is 54.1kHz
4. "1.2.4" indicates that the PWM output pulse is 124kHz

Parameter setting:

The module has four buttons [FREQ+], [FREQ-], [DUTY+] and [DUTY-] which are used to set the frequency and duty cycle.

Press the buttons to adjust the parameter value (a long press quickly adds or subtracts).

Parameter settings are automatically saved.
