The name says it all on this one. An ATmega328P in DIP package, pre-loaded 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's ATMega328P 8-Bit 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 10-bit ADC. Runs up to 20MHz with external crystal. Package can be programmed in circuit. 1.8V to 5V operating voltage!
Note: This microcontroller is in fact the ATmega328P, not the original ATmega328 and contains the bootloader used on the Arduino Uno, with small modifications to work more reliably with different serial connection options (mainly the FTDI). Check the link below for more information.
This chip is great for making breadboard Arduinos. For more information on the parts to make a breadboard Arduino and guide, check out the documentation from our old Breadboard Arduino Compatible Parts Kit:

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

This is great for those like me who are too lazy to burn the bootloader themselves but want Arduino Uno projects without the cost of an entire Uno. I use the Arduino IDE to program the chip, and then transfer it to a smaller board for projects, keeping my Arduino free to geek out with.

It works just like my uno. I was able to put it in my uno and program it then put it right in the project I was working on and it worked just fine.
Worked perfectly fine. Just plopped it in and ran with it. The sticker seems pretty flimsy though, I wouldn't mess with it too much. Wasn't too sure what I expected at the time but... it works, bottom line I guess.
Great product for beginners and for us closet electronic tinkerers. I ordered 5. Unfortunately, one of them didn't work but still I'm a loyal Sparkfun customer.
Please contact techsupport @ sparkfun. They'll be able to assist you with the malfunctioning IC.
Good packaging and delivered on time.
Picked this chip up because I wanted to build my own Arduino Uno and I did! I really liked the label showing the pin-outs. Comes in very handy. Thanks SparkFun
Excellent! Plug and play just as I was hoping. Very fast shipping!
