PIC16F84 microcontrollers are popular in many embedded projects. If you are learning to program those PICs it can be easier with project board - where common interfaces like LEDs, 7 segment display, LCD display and buttons are included.

Project board has an in-circuit programming header (ICP) - so microcontroller can be programmed directly on board - no need to unplug IC from it. Ready to use project files (including schematic, pcb and silkscreen) can be downloaded here.
