Used as a square wave signal generator produces a square wave signal for the experimental development use. 2. Used to generate the square wave signal to drive a stepper motor drive. 3. Produce adjustable pulse for the MCU to use. 4. Generating adjustable pulse to control the associated circuits. A brief description: 1. Size: 3.5CM * 4.6CM 2. The main chip: LM358; 3. Input voltage: 5V-12VDC. 4. Input Current: ? 100MA; 5. Output amplitude: close to the input voltage; 6. Frequency adjustment range: 0.07HZ-2KHZ (also cycle in about 0.45 milliseconds to 15 seconds); Frequency adjustment methods: The board has four the shorting cap can select the frequency: Plug 0 short-circuit the cap, that is, all four short circuit cap removed files for high-frequency, the longest cycle upwards to 0.3 seconds; Inserted a short circuit cap, the longest cycle can be adjusted to about 4 seconds; Inserted two short-circuit cap, the longest cycle can be adjusted to about 7 seconds; Inserted three short cap, the longest cycle can be adjusted to about 10 seconds; Inserted four short circuit cap, the longest cycle can be adjusted to about 15 seconds; 7. Duty cycle adjustment range: 0% to 100% (High / cycle); 8. Output Current: strip 9012 transistor drive capability is strong, about 500MA output current, the output can directly drive small relays or small motors; Advantages: 1. Adjustable duty cycle and frequency resolution; 2. Output with LED indication, there is no output straightforward (LED high amount, low level LED off LED flashes when the low frequency, high frequency LED will be lit, because the naked eye can not distinguish from); SHIPPING PAYMENT RETURNS FEEDBACK ABOUT US 1)All items will be shipped to your paypal address .Please update your latest address when you check out,and please make sure to provide us with correct,precise and detailed shipping address. 2)Most of the items will be shipped via Hongkong Airmail/Singapore Airmail .To US customers,we will send the package via E-packet . 3)All items will be shipped in 1-2 business days (excluding Sat,Sun & Holiday) after payment received and cleared.
