Import the Project File
------------------------

We use lceda (EasyEDA) to design the schematic and PCB layout. To preview the source project, you have two options:

Option 1: Import the `.epro` File
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- **For users in China**: Use the `lceda Pro Edition (立创eda专业版) <https://pro.lceda.cn/editor>`__ to import the `.epro` file.
- **For users in other regions**: Use the `EasyEDA Pro Edition <https://pro.easyeda.com/editor>`__ to import the `.epro` file.

Steps to Import:

1. Download the :download:`ProPrj_DOGlove_MainBoard.epro <../_static/hardware/ProPrj_DOGlove_MainBoard.epro>` file.
2. Open EasyEDA Pro and navigate to ``File → Import → EasyEDA (Professional)``.

Option 2: View on OSHWHub (Recommended for Users in China)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You can directly view the `DOGlove project on OSHWHub (立创开源硬件平台) <https://oshwhub.com/doublehan/doglove_mainboard>`__, which includes the schematics, PCB layout, and BOM. The platform also supports one-click PCB fabrication.
