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.
