PIC16F628A breadboard module for quick prototyping

This breadboard module is for PIC16F628A microcontroller and it provides access to the I/O ports and the power supply pins through male headers that can be easily inserted into a breadboard. This board will make protyping easier as the external oscillator, reset, and ICSP circuits are already implemented in the module. The layout of the module is shown below.


You can construct this board on a general purpose prototyping circuit board.
