Long Weekend Electronics Projects-PIC16F876 LCD 8 Keys LED Serial Port I2C Bus

This little circuit is pretty cool. I made two sets of these cards from one 6" x 6" pc board material. After exposing, etching and drilling I sheared the cards into individual boards. One set is in the two board configuration and the other is the 3 board setup. Front board has 2 line x 8 chars back-lit LCD display with 8 keys, a Red/Green LED all on a 2" x 3" card. It plugs into another card that has the surface mounted PIC 16F876 micro-controller and a 64K E2ROM chip. There are 8 lines that come from the board to the prototyping area card. It has as AC to DC power supply and a 5V regulator . The eight lines you connect to for various project are: 2x 10-bit Analog, 2x Digital I/O, 2x Serial port (RX/TX data), and 2x I2C device lines (SDA,SCL). I have a few project I want to build and the all need this kind of interface. The prototyping area will allow for a variety of circuits. Pretty neat eh. A programmable antler.
