Square wave signal generator NE555

Square wave signal generator that generates a square wave signal used for experimental development. Used to drive a stepper motor to generate a square wave motor signal. Generate an adjustable pulse for the MCU. Generate an adjustable pulse to control connected circuits. Features: Generate an adjustable pulse for the MCU. Generate an adjustable pulse to control connected circuits. The output current can be 15 milliamps; when the power supply is 12 volts, the output current can be 35 milliamps. About the output with an LED indicator (low level, the LED will light; high level, the LED will turn off; low frequency, the LED flashes). Maximum output current: ≥ 15MA (5-volt power supply, V-PP greater than 50%), ≥ 35MA (12-volt power supply, V-PP greater than 50%).
