After weeks of waiting, the PCB is finally here fresh from China.
It only cost me $10 for 10 panels + 2 free, each panel consist of main board and 6 RGB LED Board.
To minimize the assembly time, I design the board to use the modules instead of making new design of each modules. See bluetooth module, microSD module and Arduino Pro Mini.
Fully functional and ready for mass soldering, but I still need to complete the components and modules. :(
