   - If can run KiCAD 4 from python
   - Check `FreeRouting` API, see if a acceptable file can be generated from things on hand

+##### Approach A
+
+
+- Import to PCBnew issue:
+  - Dimension of board outlines are incorrect
+  - Pins does not fit in original drawings
+  - (solved. Microcontroller footprint was incorrect)
+
+- pipeline confirmed:
+  
+  - 1. Build symbol and footprint library for all required electrical element
+  - 2. Sketch schematic design
+    - `.sch` file
+  - 3. Place elements in required position
+    - `.dsn` file
+  - 4. Import `dsn` file into `FreeRouting` and do auto-routing
+    - `.ses` file
+  - 5. Import `ses` file back to `KiCAD` and export as `dxf` file
+    - `.dxf` file
+
+- Manually tested pipeline till step 4
+  - Record of Tips:
+    - To run `FreeRouting` from command line:
+      ~~~
+      java -jar freeRouting.jar 
+      ~~~
+- TODO:
+  - Finish with testing the pipeline manually
+  - Achieve steps directly from script (Python API)
