Variable Voltage Power Supply Using LM317 PCB Design Gerber File

Introduction This is a PCB design of an LM317 IC-based variable voltage power supply. In this PCB, you can see two screw terminal blocks. The first screw terminal block is for input, and the second screw terminal block is for output. We can connect this PCB to any fixed DC power supply to convert a fixed DC power supply into a variable output voltage power supply. The maximum input voltage for this PCB is DC 35V. Working of this PCB Let's suppose we have connected the input of this PCB to the output of a DC 24V power supply. Now, we can get a variable output voltage from the output of this PCB. We can change the output voltage of this PCB by rotating the RV1 potentiometer.

NOT Gate Based Monostable Multivibrator PCB Design

 


Introduction

This is a PCB design of a NOT gate-based monostable multivibrator circuit. In this PCB, you can see a push switch that works as an input and you can also see an LED that works as an output indicator.

Working of this PCB

When we connect this PCB to a 5V DC power source then it will start working. When we press the push switch for a short time then the LED will turn on and remain on even after we release the push switch. The LED will remain on until the RC time constant completes.

Front or Top Side View

In the image below, you can see how this PCB will appear from the top or front side after manufacturing. The components are clearly visible on the top side of the PCB in the provided image


Bottom or Back Side View

In the image below, you can see how this PCB will look from the back or bottom side after manufacturing. On the bottom side, you can observe the appearance of all solder pads.
