Hi.
I am a bit new to EasyEDA.I need design a PCB using manual method. I use BA3822 IC which has SZIP24 pin layout. pin spacing is .889 any EasyEDA doesn't allow me to out pads in this spacing.
Kindly help.
Hi Lakmal.Nishanta,
Welcome to EasyEDA.
I have just created a `BA3822LS` schematic symbol and `BA3822LS-SZIP24` PCB footprint for you.
You can find them by searching for `BA3822LS` using the **SHIFT+F** component search or the **More Libraries...** button.
* Please note that at some point you will need to draw a schematic otherwise how do you know how the PCB is to be connected up?
Please consider creating a schematic first, assigning packages to each component and then using the `Convert Project To PCB...` button:

This will save a lot of time in checking that your PCB is correct.
Creating a proper schematic also allows you to automatically generate a Bill of Materials (BOM):

It will also save a lot of time if you have to make changes to the design because you can change the schematic then use the `Import Changes...` button in the PCB whilst still being able to check the design properly.

Happy to have got you started.
BTW: Please note that the BA3822LS schematic symbol is not simulatable.
No spice model for this part exists and there is insufficient information in the datasheet from which to create a behavioural model.
