The name says it all on this one.
An ATmega328P in DIP package preloaded with the Arduino Optiboot (Uno 16MHz) Bootloader. This will allow you to use Arduino code in your custom embedded project without having to use an actual Arduino board.
To get this chip working with Arduino IDE you will need an external 16MHz crystal or resonator a 5V supply and a serial connection. If you are not comfortable doing this we recommend purchasing the Arduino Uno board that has all of these built into the board.
Atmel ATMega328P 8Bit Processor in 28 pin DIP package. It's like the ATmega168 with double the flash space. 32K of program space. 23 I/O lines 6 of which are channels for the 10bit ADC. Runs up to 20MHz with external crystal. Package can be programmed in circuit. 1.8V to 5V operating voltage!
Note: This contains the bootloader used on the Arduino Uno with small modifications to work more reliably with different serial connection options (mainly the FTDI).
