A microcontroller Development Board is a generic printed circuit board(PCB), not meant for any specific application. It usually has an interface for programming the microcontroller's flash memory, connectors for the microcontroller's I/O ports, LED banks to show the status of the I/O ports, a reset switch and a serial port or some other comm. port for talking to the outside world. But all this is optional and you can add or remove anything from it depending on your needs or application. Development Boards are very important for hobbyists and small projects.
Here is my AVR ATmega16 Development Board(target board).

If anybody wants any help with this stuff, just drop a comment or "Contact me". I'll be happy to help.
So I'll show you some of my AVR Development Boards that I've made for myself and also provide their layouts.
