Dual transceiver PCB for encoders - EasyEDA, JLCPCB and LCSC

Let's make up a quick PCB for the encoder line drivers. I can't be arsed to install anything sophisticated like Autodesk Eagle for something as simple as this. And I want to get them made at a Chinese supplier over the internet. How about EasyEDA and JLCPCB? There is also a sister company LCSC that supplies a decent range of compts, so you can order up the PCBs and components at the same time.

Firstly, create simple schematic, using the LCSC parts library It's easy to identify suitable parts, using datasheets and pics.


Either paste the part number from the LCSC site into the schematic / layout library or find it from within the schematic / layout library in the first place. Then place into the schematic. 


Here's the schematic. Doesn't get much simpler than this - one IC, one cap and 2 connectors.


Move into the layout area, place compts, route and finish off.


Here's the "photo view":


And the "3D view"


Here's the BOM in the sister site (LCSC)


And the PCB order. They will be shipped together - PCBs and compts.

Now just sit back and wait several weeks for the parts to arrive....
