Description new NE555 pulse frequency adjustable module Square wave signal generator Specification: 1. use as a square-wave signal generator, generate square wave signals used for experimental development. 2. to generate square wave signal driving stepping motor drive. 3. adjustable pulses generated for use by the MCU. 4. adjustable pulse control related circuits. Description: size: 3.5CM*3.6CM 1, Main chip: NE555; 2, Input voltage: 5V-15VDC. (When 5V power supply, output current =15MA; when 12V power supply, output current=35MA); 3, Input current: ≥ 100MA 4, the output amplitude: 4.2V V-PP to 11.4V V-PP. (according to the different input voltage, output will be different) 5, Maximum output current: ≥ 15MA (5V power supply, when V-PP is greater than 50%), ≥ 35MA (12V power supply, when V-PP is greater than 50%) Characteristics and advantages: 1, output with LED indication(low level LED ON, high level LED OFF, at lower frequencies than the LED flashing); 2, the output frequency range level can be selected, the output frequency adjustable; Low frequency: 1Hz~50Hz MF: 50Hz~1kHz HF: 1KHz~10kHz HF: 10kHz~200kHz 3, the output duty cycle can Adjustable(Small), adjustable duty ratio will change the frequency. 4, the output frequency adjustable; Cycle T=0.7 (RA+2RB) c RA, RB for the 0-10K adjustable; C=0.001UF low frequency gear; C=0.1UF MF gear; High frequency in document C=1UF; C=100UF high frequency gear, wave frequency buyers can own calculation.
