NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator

Description

Input Voltage: 5V-15VDC. when power supply is 5V , the output current can be 15MA around;when 12V
power supply, the output current can 35MA around;
Input current: >=100MA;
3.Output amplitude: 4.2V V-PP to 11.4V V-PP. (Different input voltage, the output amplitude will be different)
Maximum output current: >=15MA (5V power supply, V-PP greater than 50%), >=35MA (12V power
supply, V-PP greater than 50%)
Output with LED indication(low level ,LED will on; high level,LED will off;low frequency, the LED flashes);
The output requency range is selectable:
LF file: 1Hz ~ 50Hz IF file: 50Hz ~ 1kHz
High-frequency file: 1KHz ~ 10kHz
HF file: 10kHz ~ 200kHz
Cycle T=0.7 (RA+2RB) C (RA, RB for 0-10K adjustable):
Low frequency:C=100UF; Intermediate frequency:C=1UF;
M-H frequency: C=0.1UF; High frequency: C=0.001UF,
