Arduino Nano Every development board ATMega4809 11

SKU CH-EGMW-BGRBG

Compact development board with ATMega4809 processor and castellated pads for breadboard or surface-mount use

  • Classic Nano footprint fits existing projects
  • ATMega4809 AVR processor powers everyday tasks
  • SAMD11 ARM Cortex M0+ handles USB-serial conversion
  • Castellated pads allow direct PCB soldering
  • Headers pre-mounted for instant breadboard use

Compact development board

The Arduino Nano Every is a microcontroller board built around the ATMega4809 AVR processor. It shares the classic Nano footprint so it fits existing shields and breadboard layouts. The board ships with headers already mounted for immediate prototyping. It suits makers and engineers who need a small, 5 V logic platform for everyday embedded projects.

Simple setup with IDE support

Programs are written and uploaded through the standard Arduino IDE, available both offline and online. Thousands of open-source sketches let you start testing code in minutes. The on-board SAMD11 ARM Cortex M0+ chip handles USB-to-serial conversion and can be reprogrammed by experienced users for custom bridge firmware. Castellated pads also allow direct surface-mount soldering onto a custom PCB if a lower profile is needed.

Steady operation for long-running tasks

The AVR core delivers deterministic timing for control loops that run continuously without the overhead of an operating system. Flash memory and RAM are sized for typical sensor polling, actuator driving and communication tasks. The board draws modest current from the USB supply or an external 5 V source, making it practical for battery-powered or always-on installations. Thermal load remains low during sustained workloads.

Questions about this item

How do I confirm the ATMega4809 board is running correctly after uploading a sketch?

The on-board LED will blink if the default sketch uploads successfully, and the Arduino IDE serial monitor will show output from your code.

What does the package include and what must I source separately?

The board arrives with headers already mounted. A USB cable and any sensors or actuators are not included.

Which version should I pick for a compact project needing more program space?

The ATMega4809 variant provides the classic Nano footprint with increased flash and a re-programmable SAMD11 USB bridge.
