NE555 Duty Cycle Frequency Adjustable Square Wave Signal Generator Board Module

Features: Product Details: Signal Generator Module Condition: New Scope of this module: 1 Used as a square wave signal generator generates a square wave signal used for experimental development. 2 To drive a stepper motor for generating a square wave drive signal. 3 Adjustable pulse generated for MCU. 4 Adjustable pulse generation, control circuitry associated   Description: 1 Size: approx.3.1CM * 2.2CM 2 Main chip: NE555; 3 Input voltage: 5V-15VDC. When 5V power supply, the output current can 15MA around; When 12V power supply, the output current can 35MA around; 4 Input current: ≥ 100MA 5 Output range: 4.2V V-PP to 11.4V V-PP. (Different input voltage cause different output) 6 Maximum output current: ≥ 15MA (when 5V power supply, V-PP greater than 50%), ≥ 35MA (when 12V power supply, V-PP greater than 50%)   Advantages: 1 Output with LED indication, easy to see(low volume LED will light, high volume LED will off, LED flash when frequency is relatively low)
