ZK-PP1K PWM Pulse Frequency Duty Cycle Adjustable Module Square Wave Rectangular Wave Signal Generator

The module is built with: NE555 chip; Working voltage: 5-30V; Supports Micro-USB 5.0V power supply
Frequency range: 1Hz-150KHz; Frequency accuracy: ±2%
Two independent PWM generators: Can set frequency, duty cycle, wide frequency range, high accuracy, with serial communication
Output current:
Working temperature range: -30 to +70 °C;
Serial control: Baud rate: 9600 bps; Data bits: 8; Stop bits: 1; Parity bits: none; Flow control: none
Details: Parameter setting: The module has three buttons: [Set], [Up], [Down]. Press the [Set] button to switch keys (FR1: PWM1 frequency; dU1: PWM1 duty cycle; FR2: PWM2 frequency; dU2: PWM2 duty cycle). Press the [Up], [Down] buttons to change (long press can quickly add or subtract).
Frequency ranges: 1.XXX (integer): minimum unit is 1Hz, range is 1Hz - 999Hz. X.XX (decimal with one decimal place): minimum unit is 0.1kHz, range is 0.1kHz - 99.9kHz. X.X.X (decimal with two decimal places): minimum unit is 1kHz, range is 1kHz - 150kHz. Frequency display examples: "1.100" PWM output 100Hz. "54.1" PWM output 54.1kHz. "1.2.4" PWM output 124kHz.
Duty cycle in range 0 to 100.
Application areas: Square wave signal generator. Square wave signal generation for motor driver. Adjustable pulse generation for chip usage. Adjustable pulse generation for controlling related circuits (PWM dimming, speed regulation).
Setting examples: "1.S1FXXXKT": set PWM1 frequency XXX HZ (001-999). "2.S1FXXXKT": set PWM1 frequency XXX KHZ (00.1-99.9). "3.S1F:X.XXKT": set PWM1 frequency XXX KHZ (0.0.1-1.5.0). "4.S1:PWM1 5.F": Frequency 5.F. "6.D: Duty Cycle 7.T": 'T' is the end character. Set PWM duty cycle 7. "1.S1DXXXKT": set PWM1 duty cycle XXX (001-100). "2.S2DXXXKT": set PWM2 duty cycle XXX (001-100). Successful setting returns: DOWN; Setting return: FAIL.
