Application scope: 1. Used as a square wave signal generator produces a square wave signal for the experimental development use. 2. A square wave signal is used to produce a stepper motor-driven drive. 3. Produce the adjustable pulse for MCU use. 4. Generates the adjustable pulse to control the associated circuits. Description: 1. The main chip: LM358. 2. Input voltage: 5V-12VDC. 3. The input current: ?Y 100MA. 4. The output amplitude: close to the input voltage. 5. The frequency adjustment range: 0.07HZ-2KHZ (also cycle in about 0.45ms to 15s). 6. Duty cycle adjustment range: 0% to 100% (High / cycle). 7. Output Current: strip 9012 transistor drive capability is strong, about 500MA output current, the output can directly drive small relays or small motors.
