Main chip: NE 555;
Input Voltage: 5 V - 15 VDC.
When power supply is 5 V, the output current can be 15 MA around;
When 12V power supply, the output current can 35MA around;
Input current:> = 100 MA
Output amplitude: 4.2 V V - PP to 11.4 V V - PP. (Different input voltage, the output amplitude will be different)
Output with LED indication (low level, LED will on (Maximum output current:> = 15 MA (when 5 V power supply, V-PP greater than 50%),> = 35 MA ;
High level, LED will off; low frequency, the LED flashes);
