The ATmegaXX8 Target Boards are low cost and convenient target/breakout boards for Atmel AVR microcontrollers. Fits ATmega48, ATmega88, ATmega168, and ATmega328 microcontrollers. These ATmegaXX8 Mini development kits each contain a ATmegaXX8 Target Board and some other parts to help you get started. These Zero Insertion Force (ZIF) sockets clamp onto a chip, making a good electrical connection, when you push the lever down. When you release the lever, it releases the chip. This allows you to repeatedly insert or remove a chip from the socket without damage to either. These 28-pin ZIF sockets are perfect for working with chips in narrow 0.3" wide DIP packages with up to 28 pins, including the popular ATmega48/88/168 series of AVR microcontrollers. When using ZIF sockets, keep in mind that the pins are a bit wider than regular IC pins. -- they fit in most pad-per-hole type prototyping boards, but may not fit in a chip socket or circuit board that was meant to hold a chip alone.
