On the left hand Navigation panel you will find “EElib“ and “Libraries“ ,
That contains ready made symbols for a wide range of components and which can be simulated.
Many of these components have optional US and EU style symbols, we split them, so you can select those you like. Click on the drop down list or right click to popup the context menu, it contains many packages or parameters. EasyEDA will remember your choices for the next time.
Don’t forget to use Filter to locate a component fast. For example, you just need to type
res to find all of resistors:
or press the hotkey combination
then you will see a dialog as shown in the image below.
The more information please refer next “Libraries” section.
Finding individual components in a dense schematic can be very time consuming. EasyEDA has an easy way to find and jump to components:
Topbar > View > Find…
Note: You have to click OK in this dialog or use the Enter key.
This feature will find, highlight and center in the window, parts by their Prefix (or reference designator). However, it cannot be used to find net names or other text in a schematic.
This is where the Design Manager comes in.
Left Navigation Panel > Design Manager, or use hotkey
The Schematic Design Manager is a very powerful tool for finding components, nets and pins.
Clicking on a Component item highlights the component and pans it to the center of the window.
Clicking on a Part pins item brings up a temporary pointer:
Find the component which you plan to place to your schematic at “Libraries”, then move your mouse to the canvas and left click. If you want to add more, just left click again. To end the current sequence of placements, right click once or press
Don’t try to Drag and Drop a component to the canvas: EasyEDA team thinks that Click-Click to place components will be easier to use than a Click-Drag mode.
The number of pins on some components can be quite large. That’s why it’s easier to divide such a component into several parts or functional blocks. As a simple example, there are six gates in the 74HC04 Hex Inverter component. To avoid clutter in the schematic, GND and VCC pins of such components are usually served by a separate part of the component. This is really convenient as it doesn’t interfere the working process with logical parts. The NetLabel names of VCC and GND Pin are usually hidden.
When placing the 74HC04 on a schematic, it will look like the screenshot below.
Note: The component Prefix will be in form of: U?.1, U?.2 etc.
How many times have you hit a schematic capture roadblock because you couldn’t find a component symbol?
Well, in EasyEDA that would be never because the Schematic Library Wizard provides a quick and easy way to create a general schematic library symbol.
The Schematic Library Wizard… command can be found in the top toolbar.
Or Edit > Schematic Library Wizard in a new schematic lib document.
Using the NE555 timer as an example: this device is available in a DIP8 package so select DIP. Then enter the NE555 pin names into the Pin Names text box separated by new line or space, Then press OK. Abracadabra! As if by magic, you will find a perfectly formed dual in line 8 pin symbol for the NE555 attached to your mouse cursor, ready to be placed! You just need a few seconds to build a NE555 symbol, quickly and easily.
The EasyEDA Schematic Symbol Wizard allows you to create DIP, QPF or SIP styles symbols. If you are designing Arduino Shields then you will need lots of SIP symbol, so you can create a SIP symbol like the one shown below in a few seconds.
If you are not too worried that the symbols may not look quite the way people might expect and that they may not look anything like the Package type you enter, then of course you can use the wizard to create symbols for any component:
