NE555 Pulse Generator Pulse Starter Duty Cycle and Frequency Adjustable Module DIY Kit Oscillator Square Wave Signal Generator

modname=ckeditormodname=ckeditor1、 Scope of application of this module: 1. Used as a square wave signal generator to generate square wave signals for experimental development. 2. Used to generate square wave signals for driving stepper motor drivers. 3. Generate adjustable pulses for MCU use. 4. Generate adjustable pulses to control related circuits. 2、 Brief description: 1. Size: 3.1CM * 3CM 2. Main chip: NE555; 3. 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; 4. Input current: ≥ 100MA 5. Output amplitude: 4.2V V-PP to 11.4V V-PP. (The output amplitude may vary depending on the input voltage) 6. Output current: ≥ 15MA (5V power supply, V-PP greater than 50%), ≥ 35MA (12V power supply, V-PP greater than 50%) Three characteristics: 1. Output with LED indicator, whether there is output is directly clear (LED quantity at low level, LED off at high level, LED flashing at low frequency); 2. The output frequency range and grade can be selected to make the output frequency more continuous and adjustable; (Due to the slight deviation between components, the color of the components may also deviate slightly, but it does not affect the use) Low frequency range: 1Hz~50Hz Mid frequency range: 50Hz~1kHz Mid to high frequency range: 1KHz to 10kHz High frequency range: 10kHz~200kHz 3. Adjustable output frequency; Cycle T=0.7 (RA+2RB) C RA and RB are adjustable from 0-10K; At low frequency, C=0.001UF; C=0.1UF in mid frequency range; Mid to high frequency range C=1UF; At high frequency, C=100UF, so buyers can calculate the frequency of the waveform themselves.
