After building my first development board I decided to build a second one. This one is going to work with a PIC16F877
The functions will be:
-7x Led
-8x dipswitch
-2x 7 segment display
-1x Lcd
-1x RS232 connection
-1x program plug (wisp or pickit layout, depending on installed connector)
I have placed 2 rows of female header cups next to the pic, to make it easy to connect this board to a breadboard.
Some pictures from the first prototype:

The serial interface and the lcd are also working already:
For the final version I had this pcb professionally etched:
