HW-515 DC 2CH PWM Signal Generator Module

Dual-Channel Independent PWM Outputs: Provides two independent PWM channels with individually configurable frequency and duty cycle parameters, ideal for driving dual motors or multi-load testing.

Wide Frequency Range (1Hz – 150kHz): Generates adjustable pulse-width modulation frequencies spanning from 1 Hz up to 150kHz with high precision across all range bands.

Integrated 3-Digit Blue LED Displays: Clear, easy-to-read dual 3-digit LED displays provide instant, real-time readouts of operational frequency and duty cycle settings (0% - 100%).

Serial UART Communication Support: Built-in TTL serial communication port enables remote PC or microcontroller adjustment of frequency, duty cycle, and output states.

Tactile Pushbutton Adjustments: Features dedicated front-panel pushbuttons for fast, intuitive configuration of frequency increments and duty cycle percentages.

Power-Off Memory Retention: Automatically saves all set parameters upon power loss, restoring previous settings instantly when powered back on.

Board & Hardware Construction: Compact double-sided FR4 PCB with surface-mount driver components, dual 3-digit 7-segment LED displays, Micro-USB power port, and screw terminal blocks.

Technical Specifications:

Operating Voltage: 5V - 30V DC (Supports Micro-USB 5V power supply).

Frequency Range: 1Hz - 150kHz.

Frequency Accuracy: Approx. 2% across each range band.

Duty Cycle Range: 0% - 100% continuously adjustable.

Output Signal Current: 5mA - 30mA.

Output Voltage Amplitude: Equal to input supply voltage.

Usage Advice: Verify that load current requirements do not exceed 30mA per channel; use external MOSFETs or relay modules when controlling high-power motors or heavy loads.

Handling & Cleaning: Protect circuit traces against electrostatic discharge (ESD) and moisture. Clean display surface and PCB gently with a dry microfiber cloth.

Essential PWM Control Module for Robotics & Automation: Position as a versatile, low-cost signal source for controlling DC motor speed, LED dimming, stepper motor drivers, and power switching circuits.

Highlight Dual-Channel Independence & Serial Control: Emphasize its 2 independent channel control and TTL serial programming capability as key advantages over basic single-channel timer modules.

Recommended Cross-Sell Add-ons: Pair with XY-LPWM Signal Generator PWM 1Hz-150Khz 3.3V-30V Pulse Frequency Duty Cycle LCD, NE555 Pulse Frequency Duty Cycle Adj. Square Wave Signal Generator, AD9850 DDS Signal Generator Module, and ICL8038 Monolithic Function Signal Generator Module.
