Welcome to my ebay store! You will find your favorite products. Pass by do not miss.thank you! Product Detail ( ---☆ ayanhu81 ebay shop welcome you to buy it ☆---) Note: This product is not a sophisticated circuit, is not suitable for use where high precision. Board Color : Green or Blue , send by random Applications: ( ---☆ ayanhu81 ebay shop welcome you to buy it ☆---) 1. As square wave signal generator generates a square wave signal for experimental development use. 2. used to generate drive a stepper motor drive square wave signal. 3. produce an adjustable pulse for MCU to use. 4. Have an adjustable pulse control-related circuits. Explanation: ( ---☆ ayanhu81 ebay shop welcome you to buy it ☆---) 1, Size: 35x33mm 2, the main chip: NE555; 3, the input voltage: 5V-15VDC. 5V supply, the output current can be around 15MA; when 12V power supply, output current is about 35MA; 4, the input current: ≥100MA; 5, the output amplitude: 4.2V V-PP to 11.4V V-PP (different depending on the input voltage, the output amplitude will be different);. 6, the maximum output current: ≥15MA (5V supply, V-PP is greater than 50%), ≥35MA (12V power supply, V-PP is greater than 50%); Advantages: ( ---☆ ayanhu81 ebay shop welcome you to buy it ☆---) 1, the output with LED indication, there is no straightforward output (low level LED lights, LED off at a high level, LED blink rate is relatively low); 2, the output frequency range of grades available, so that the output frequency is more continuously adjustable; Low-profile: 1Hz-50Hz IF file: 50Hz-1kHz High-frequency gear: 1KHz-10kHz High Frequency file: 10kHz-200kHz 3, the output frequency is adjustable; Cycle T = 0.7 (RA + 2RB) C VR1, VR2 is 0-10K adjustable; When the low-profile C = 0.001UF; When IF shift C = 0.1UF; High-frequency gear C = 1UF; When high-frequency gear C = 100UF, therefore frequency waveform buyers can own calculations.
