NE555 Pulse Frequency Duty Cycle Adjustable Module
Square Wave Signal Generator Size: 31mm * 22mm;
Main chip: NE555; 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 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, The output duty cycle can fine-tune;duty cycle
and frequency is not separately adjustable;adjusting the duty cycle will
change the
