This is the CHIPAXE 18-pin module in kit form without the Microcontroller.
It will accept any of the PIC16F 18pin Microcontrollers and even most PIC18F 18 pin parts. The header allows it to plug directly into a PICkit 2 or PICkit 3 programmer for easy development. The pins are 0.1" pitch so it can easily be plugged into a breadboard.
