Design two PCB projects in EasyEDA—from idea to order—covering a powerbank charger and a 12-volt DC power supply; derive schematics from IC datasheets, route, and export BOM and Gerber files.
Explore how transistors, transformers, and inductors drive switching, energy transfer, and impedance matching in pcb design.
Make a bit corrections here:
1 ) Consider here 17V AC instead of 14V AC in explanations.
2) Drop out voltage for this Regulator is 2V so i/p and o/p voltage difference should be minimum 2V , this much voltage is required to maintain smooth output for power supply. In our case Ripples 15.6V DC will be input and output will be smooth 12v DC.
Learn to start your first EasyEDA project, log in with Gmail or Hotmail, save a 12 volt dc power supply, and manage sheets while exploring the common library components.
Learn to place a two-pin header, set its prefix and visibility, and design a four-diode rectifier using SMD components while distinguishing surface-mount and through-hole options.
Read the voltage regulator datasheet to select a 12 V regulator, considering input/output voltages, dropout, protection, and the datasheet’s two capacitors on input and output for stability.
Design a 12v dc circuit schematic in easyeda by placing a voltage regulator, capacitors, diodes, led, resistor, and header; connect components with the wiring tool, zoom for accuracy, and save.
Convert a schematic to a two-layer pcb in EasyEDA, review DRC rules, explore 2d/3d views, place smd components and headers, and route with 45-degree angles to optimize traces.
Generate Gerber and PCB fabrication files, verify DRC, and order five PCBs, two-layer PCB, in blue with silkscreen, without assembly, at a low per-board price.
Learn to work with the bill of materials, identify in-stock parts from LCSC and JLCPCB libraries, evaluate part match confidence, and place orders or adjust as needed.
Design a powerbank charger PCB with EasyEDA, from schematic design and data-sheet selection to final layout, covering USB input, Li-ion battery charging, and a 5-V output.
Explain a block diagram for a powerbank charger that boosts 3.7V Li-ion to five volts using a boost converter IC, potentiometer, and Zener diode, with USB/microUSB input.
Select a battery management ic from the datasheet to charge a 3.7 v li-ion battery, using a boost converter and related power management components.
Select in-stock resistors and capacitors using EasyEDA and JLCPCB libraries. Learn to choose 1 kilo-ohm 0402 resistors and 1 microfarad, 4.7 microfarad, 220 microfarad capacitors for the project.
Learn how to select a Zener diode for a 5-volt output using EasyEDA and JLCPCB libraries. Understand choosing diodes within 4.5 to 5.5 volts, reading datasheets, and using part numbers.
Select and place an NTC thermistor for the tp4056m charger, verify pin configuration in the library, reference the data sheet, and establish consistent schematic names for clear pcb routing.
Explore two-layer pcb routing in easyeda by converting schematic to pcb, comparing random versus accurate component placement, and using auto routing to minimize vias and improve connections.
Order a two-part pcb project by generating gerber files and a bill of materials with in-stock LCSC parts, then use one-click ordering on JLCPCB for the pcb and components.
In this course, we will design PCB of 2 projects from start till end. We will design Power Bank Battery Charger and 12V DC power supply. How we can think to get the idea of schematic diagram of projects ? We will not do only copy paste of schematic diagram but also you will get complete explanation from where you will get the idea for this schematic. The use of each component and its purpose is clearly explained in these projects. So if you want to use them later in different projects then you can easily apply there.
The selection of each components on the basis of Datasheet will be discussed in detail. The parameters to select each component. PCB routing and layout for both projects will be described. The calculation for selecting the width of routing is also explained well.
How we can order the BOM for in stock and out of stock components. Different ICs will be used in these projects. We will get detailed overview of each IC with the help of Datasheet.
A brief introduction of few basic electronics components is also explained.
Importance of PCB designing and its online big market in freelancing is also described well with a separate video.
There is a Quizz and Assignment for self-assessment, by which you can improve your learning path for PCB designing.
