Product Description


ATMegaZero Logo

The ATMegaZero is a microcontroller board based on the ATMega32U4 microchip, the same chip used in the Arduino Leonardo and Arduino Micro. It was modeled after the Raspberry PI Zero to take advantage of its sleek design and form factor but in the form of a microcontroller board.

Similar to the Raspberry Pi Zero the ATMegaZero comes with 40 GPIO pins that can be used as input or output for interfacing devices and can be programmed using the Arduino IDE software.

Because the ATMegaZero was modeled after the Raspberry Pi Zero it will fit perfectly on any existing Raspberry Pi Zero cases.



The ATMegaZero was designed with makers in mind and here are some of the key specs that make this a great microcontroller board:

  • Core: ATmega32U4 microcontroller running at 16MHz
  • Memory: 32KB Flash, 2.5KB SRAM, 1KB EEPROM
  • GPIO: 40 pins header
  • Digital I/O: 17
  • Analog Input: 6
  • GND pins: 8
  • +3V3 pins: 2
  • +5V pins: 2
  • ESP-01 GPIO pins: 2 (direct access to these two pins)
  • Communication: UART/SPI/I2C
  • Micro SD Card module for reading/writing data (Micro SD card not included)
  • 32 pins OLED Display port (compatible with 30 pins SSD1306​ & ​SSD1331)
  • Pinout for connecting an ESP-01 WIFI Module
  • Operating Voltage: 5V
  • Dimensions: 2.6"x1.2" (65mmx30mm)
  • Weight: 0.5oz
  • Software: Works out of the box with the Arduino IDE (Win/OSX/Linux)

    Do you know which country are the manufactured? I tried to looks information online but I got nothing.

    The board was designed in the United State and will be assembled in Shenzhen, China. Thanks for asking.

    The preview photo for the video on the project page shows a color-coded 2x20 header - are those available? The ones available as a add-on (and the ones actually in the video) are just black...

    @CatFood, great question. The colorful ones are not included and I wasn't able to get them in bulk to include it as an Addon. The only one available was black. I'm planning to find a manufacturer that can do them in bulk and will have them available for sale from my website after the campaign ends. Thanks for the question.
