These are Agon light™'s design files.

The schematics are provided as a separate PDF file, Schematic_AgonLight_R1.0.pdf.

The EasyEDA source files, with extension .json, are also provided above, for both the schematics and PCB layout. These can be imported directly into EasyEDA, for maximum convenience, if you plan on re-using Agon light™'s design to develop your own variant.

The file AgonLight_R1.0_EasyEDA_Backup.zip is redundant, and simply provides a ZIP archive of the EasyEDA source files.

Finally, the file AgonLight_R1.0_Layers&Traces.pdf contains a PDF illustration of the PCB layout.
