## Description

A pre-programmed ATmega328P chip with the Adafruit 'ADAboot' bootloader, ready to drop into an Arduino Uno, Duemilanove, Diecimila, or NG board. Use it to replace a damaged chip or build your own Arduino-compatible project on a breadboard or custom PCB. The ADAboot bootloader is compatible with the standard Arduino bootloader but includes a quick-start modification — after uploading a new sketch, it begins immediately without the usual delay. A 5-second delay still occurs after pressing reset or opening the serial port, but sending any character other than ASCII '0' will skip the delay and start the application immediately. Key Features Pre-programmed ATmega328P – Ready to use with no additional programming required ADAboot Bootloader – Quick-start compatible with NG, Diecimila, Duemilanove, and Uno 57600 Baud Upload – Fast sketch uploading speed Auto-Reset Support – Works with Arduino IDE version 009 and later Drop-In Replacement – Standard DIP-28 package fits existing Arduino sockets Compatibility Arduino Uno Arduino Duemilanove Arduino Diecimila Arduino NG Freeduino and compatible clones Package Contents 1× ATmega328P with ADAboot bootloader Tip: Select "Duemilanove with ATmega328" in the Arduino IDE when uploading sketches to this chip.
