NE555 Signal Generator Square Wave Pulse Frequency Adjustable Module 1~500KHz

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.
