5Pcs NE555 Pulse Frequency Duty Cycle Adjustable Module Rectangular Square Wave Signal Generator Stepper Motor Driver Board Module NE555 Pulse Generator

Product parameters: 1. Main chip: NE555 2. Input voltage: 5V-15VDC, when powered by 5V, the output current can be around 15MA; when powered by 12V, the output current can be around 35MA; 3. Input current: greater than or equal to 100MA 4. Output amplitude: 4.2V V-PP to 11.4V V-PP (depending on the input voltage, the output amplitude will be different) 5. Maximum output current: greater than or equal to 15MA (5V power supply, when V-PP is greater than 50%), greater than or equal to 35MA (12V power supply, when V-PP is greater than 50%) Advantages: 1. The output has LED indication, and it is clear whether there is any output (the LED is on when the low level is on, the LED is off when the high level is off, and the LED flashes when the frequency is relatively low) 2. The output frequency range is optional, making the output frequency more continuously adjustable; Low frequency file: 1Hz～50Hz IF file: 50Hz～1kHz Medium and high frequency range: 1KHz～10kHz High frequency file: 10kHz～200kHz 3. The output duty cycle can be fine-tuned. The duty cycle and frequency are not adjustable separately. Adjusting the duty cycle will change the frequency; 4. The output frequency is adjustable; Period T=0.7(RA+2RB)C RA and RB are adjustable from 0 to 10K; C=0.001UF at low frequency; C=0.1UF at intermediate frequency; Medium and high frequency range C=1UF; C=100UF at high frequency, Package includes: 5 x NE555 Pulse Frequency Duty Cycle Adjustable Module 1 x 15pin Female to Male Dupont Cable
