아두이노 UNO에 사용되는 ATmega328P 칩에 Optiboot 부트로더를 프로그래밍해 놓은 마이크로콘트롤러칩입니다.

UNO보드 자작을 하실 경우나,  UNO보드를 사용하다가 메인 MCU칩이 고장이 난 경우, 본 칩으로 교환해서 설치해주시면 정상 이용이 가능합니다.  (물론 다른 부품이 고장난 경우엔 복구 안됩니다.)

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.
