Project Description:
********************
Using this 5V and 3A power supply, you can power up all your controller boards, like Arduino, ESP8266, ESP32, Raspberry Pi Pico, ESP32 Camera Module, STM32, and so on. Besides this, you can also use this 5V power supply for charging your cell phones. You can power up your Portable Displays, you can power up your robots, servo motors, LED strips, and so many other input and output modules. In this video, I am going to share with you every bit of information like for example in which software I designed this PCB, How I generated the Gerber files, How I placed online order ON JLCPCB website, from where I purchased all these tiny SMD components, how I did the soldering, and in the end, I will practically test it with different loads.

Let me tell you in detail why I needed to make this 5V 3A Power supply module. Right from the beginning, I have been using 7805 voltage regulator for powering up my development boards. This is the Arduino Nano development board which I use for testing my Arduino based projects and you can see, it has this 7805 voltage regulator. The same exact 5V power supply you will also find in my ESP32 WiFi + Bluetooth module development, I also used it with Nodemcu ESP8266, and the same exact voltage regulator I also used in my ESP32 Camera development board.
