3pcs DIY NE555 Square Wave Signal Generator Pulse Generator Electronic Production Kits With Square Wave Output

Parameter: Main chip: NE555 Input voltage: DC 5V-15V Input current 100MA Output current: 15MA-35MA Output amplitude: 4.2V-11.4V V-PP Maximum output current: 15MA (5V supply, V-PP greater than 50%) 35MA (12V supply, V-PP greater than 50%) Application scope: 1. It is used as a square wave signal generator to generate square wave signals for experimental development and use. 2. Used to generate a square wave signal that drives a stepper motor driver. 3. Generate adjustable pulses for use by the MCU. 4. Generate adjustable pulses to control the associated circuitry. Features: 1. Output with LED indication; (the LED is on when in the low level, the LED is on when in the high level, and the LED is flashing when the frequency is low) 2. The output frequency range is optional (use the short-circuit cap) to make the output frequency more continuously adjustable; low frequency range: 1Hz - 50Hz intermediate frequency range: 50Hz - 1kHz high frequency range: 1KHz - 10kHz high frequency range: 10kHz - 200kHz 3. The output duty cycle can be fine-tuned, the duty cycle and frequency are not separately adjustable, and the duty cycle is adjusted to change the frequency. 4. The output frequency is adjustable; cycle T=0.7(RA+2RB)C RA, RB is 0-10K adjustable; C=0.001UF at low frequency; in the middle frequency range, C=0.1UF; in the high-frequency file C=1UF; high frequency file C=100UF Package included: 3 X DIY NE555 square wave signal generator pulse generator kits
