2. Brief description:
1. Size: 3.1CM*2.2CM
1. Main chip: NE555;
2. Input voltage: 5V-15VDC. When 5V power supply, the output current can be around 15MA; when 12V power supply, the output current can be around 35MA;

3. Input current: ≥100MA
4. Output amplitude: 4.2V V-PP to 11.4V V-PP. (The output amplitude will be different depending on the input voltage)
5. Maximum output current: ≥15MA (5V power supply, V -When PP is greater than 50%), ≥35MA (12V power supply, when V-PP is greater than 50%)

 
Three advantages te point:
1. The output has LED indication, whether there is output is directly clear (LED quantity at low level, LED at high level is off, LED flashes when frequency is relatively low);
2. Output frequency range grade is selectable, making 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, adjusting the duty cycle will change the frequency;

4. Adjustable output frequency;
period T=0.7(RA+2RB)C 

RA and RB are adjustable from 0-10K; 

C=0.001UF in low-frequency gear; C=0.1UF in
mid-frequency gear;
C=1UF in middle- and
high-frequency gear; C=100UF in high-frequency gear, so buyers of frequency of waveform can calculate by themselves.
