LDTR - WG0004 NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator, NE555 Square Wave Signal Generator

1. Used as a square wave signal generator, which produces square wave signals for experimental development.
2. Used to generate square wave signals that can drive the stepper motor .
3. The adjustable pulse is generated for use of MCU.
4. Generate adjustable pulses to control the related circuits.
5. NOTE :When using a jumper cap to change the frequency, please cut off the power first, wait for the jump cap and then reconnect.
