PIC16F877A development and test board
Here is a very basic PCB layout for a simple PIC16F877A development and testing board. It has a voltage regulator and connector, ability to connect LEDs and inputs (switches) to any PORT, few jumpers and a crystal.
This is very useful for beginners and for prototyping with PIC for those who don't have a more serious development board.
There is also an Eagle version of this PCB with ICSP connector for easy FLASH re-programming.
