Description: The name says it all on this one. An ATmega328 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 ATMega328 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 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.

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.
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.
Good packaging and delivered on time.
Excellent! Plug and play just as I was hoping. Very fast shipping!
