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.

200 Amp High Watt PWM Based DC Motor Speed Controller PCB

 

Introduction

In the above image, you can see a PCB that is a high-wattage PWM-based DC motor speed controller. This PCB can control the speed of any DC motor with a voltage rating of less than 35 volts. In this PCB, you can observe P+ and P- terminals. Both of these terminals are the power terminals of this PCB. We need to connect these terminals to a DC power source according to the DC motor voltage rating. Additionally, you can identify M+ and M- terminals on this PCB. Both of these terminals serve as output terminals. We need to connect these terminals to a DC motor.
