ITEM NAME:NE555 Signal Generator Pulse Frequency Duty Cycle Adjustable Module LED display NE555 Pulse Frequency Duty Cycle Adjustable Module Stepping Motor Driver Board Description 1. LED display, low power frequency-light, high power frequency-goes out, relatively low power frequency-flashing. 2. The output frequency range grade is optional, make it more continuous and adjustable. Low frequency range: 1Hz ~ 50Hz Middle frequency range: 50Hz ~ 1kHz Middle high frequency range: 1KHz ~ 10kHz High frequency range: 10kHz ~ 200kHz Specification Size: 3.1*2.2cm/1.22*0.87inch Main chip: NE555 Input voltage: 5V-15VDC Current: 5V 15MA/12V 35MA Input current: ≠¥100MA Output amplitude: 4.2V V-PP to 11.4V V-PP (Depending on the input voltage, the output amplitude will be different) Maximum output current: ≠¥15MA (5V power supply, V-PP greater than 50%); ≠¥35MA (12V power supply, V-PP greater than 50%) Application: 1. Used as a square wave signal generator, offer the square wave signal for the use of the experimental development. 2. Used to produce driving stepper motor drives, offer the square wave signal. 3. Adjustable pulse for the use of MCU. 4. Generate adjustable pulse control circuit. Package includes: 1 * Pulse module.NE555 Pulse Frequency Duty Cycle Adjustable Module Stepping Motor Driver Board. Main chip: NE555. Anyway we will try our best to avoid this kind of thing. Adjustable pulse for the use of MCU. The output frequency range grade is optional, make it more continuous and adjustable.
