This is the same Atmel AVR ATmega328P microcontroller used in the official Arduino Uno, as well as our Eleven, EtherTen, USBDroid, and other boards. Perfect for building your own Arduino-compatible project directly on a breadboard or on a custom PCB, or for replacing the MCU in an existing board.

Comes with the Arduino Uno bootloader pre-installed.

Better still, it even has a special label stuck on top with details of the pinout, so you don't even need to look up the datasheet when connecting it up in your project!


  • Arduino bootloader
  • Handy pinout label on top
  • 23 programmable I/O lines
  • 6-channel ADC
  • 0 - [email protected] - 5.5V, 0 - [email protected] - 5.5.V, 0 - 20MHz @ 4.5 - 5.5V
  • 28-pin DIP format for easy use in breadboards or Arduino-compatible boards

  • Making a dumb coffee grinder slightly less dumb. This is a programmable timer tethered to a Rancilio Rocky coffee grinder. The Rocky is a "dumb" grinder and electrically very simple. Basically it's an ac motor with an on/off switch and a momentary push-button to grind. This project adds an electronic timer so that repeatable grind quantities can be produced without having to stand over the grinder. Features: - Four programmable ...

  1. Review by Robin verified purchaser

    Supplied bootloader requires a crystal, so drop it in to an existing Uno board to burn a new internal oscillator bootloader, and you have a 'zero external components required' Arduino ;) (Posted on 22/12/2017)

    I have a few of these now, for diy Arduino boards (Posted on 21/11/2017)
