NE555 Digital Squarewave Signal Pulse
Description:
This module is the frequency and variable duty cycle square pulse generator can be used in the laboratory require a square wave pulse signal, the stepper motor driver board needed to repair the master requires a pulse generator and other occasions.
Baby Description:
1, the main chip: When using ST's original base NE555 integrated IC, operating voltage of 4.5V ~ 18V, 5V supply, the output current can be around 15MA; when 12V power supply, output current is about 35MA;
2, frequency adjustment: Use two 50K variable resistor adjusts the frequency and duty cycle;
3, the fourth gear Frequency range: using pin shorting select four different ways to change the frequency range capacity capacitor, respectively (in Hz) 0.1 ~ 10,10 ~ 1K, 100 ~ 10K, 10K ~ 1M;
4, strip an LED indicator to indicate the pulse changes (low lighting), and also as a power indicator light;
5, interface with terminal mode, adapt to a variety of occasions;
6, board size: 40.5mmx22mm, a fixed diameter hole 4 3MM;.
