Product Details
✓Pulse generator module operating voltage range is DC 3.3-30V, adjustable pwm frequency range is 1Hz-150kHz, adjustable duty ratio range is 0%-100%.
✓Application: it can be used as a square wave signal generator, generate square wave signal for experimental development; generate square wave signal to control the motor driver; generate adjustable pulse for MCU; generate adjustable pulse to control the relevant circuit (PWM dimming speed application etc).
✓High Frequency Resolution: frequency in range 1Hz~999Hz, display resolution is 1Hz; range 1.00kHz~9.99kHz, display resolution is 0.01kHz; range 10.0kHz~99.9kHz, display resolution is 0.1kHz; range 1kHz~150kHz, display resolution is 1kHz.
✓TTL Level Communication: the frequency meter is designed with single-chip TTL level communication, communication standard is 9600 bps.
✓LCD Display: the blue LCD clearly displays frequency and duty ratio, PWM output can set frequency and duty ratio independently.
