4 Pieces Ne555 Pulse Frequency Square Rectangular Signal Generator Module

Main chip: Ne555;

Input Voltage: 5 V - 15 V

When power supply is 5 V, the output current can be 15mA around;

When 12 V power supply, the output current can 35mA around;

Input current:> = 100 mA

Output amplitude: 4.2 V V - P P to 11.4 V V - P P. (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 - P P greater than 50%),> = 35 mA ;

High level, LED will off; low frequency, the LED flashes);
