NE555 Pulse Frequency Duty Cycle Adjustable Module Wave Signal Generator, 501 Original

Features: LED Output Indicator: Shows the output frequency clearly with LED light ON/OFF/Flashing Four optional frequency level: Low frequency (1-50Hz), medium Frequency (50Hz-1kHz), medium-high frequency (1kHz-10kHz), and high frequency(10kHz-200kHz). Fine adjustable duty ratio: the duty ratio and frequency can not be adjusted respectively, adjusting the duty cycle will change the frequency. Used as square wave generator for experimental development, motor driver, MCU pulse, circuit control.
