Powered by the ATMega4809 running at 20MHz, it offers 48KB flash (50% more than the UNO) and 6KB SRAM (200% more), making it a significant step up from ATmega328P-based boards while maintaining 5V compatibility. At just 45×18mm, the Nano Every fits directly into breadboards and features 14 digital I/O pins (5 with PWM), 8 analog inputs, SPI, I2C, and UART interfaces. It connects via Micro USB and is available with or without pre-soldered headers, making it suitable for both prototyping and direct PCB integration. The board is ideal for space-constrained projects, wearables, robotics, and educational use where WiFi connectivity isn't needed but compact size and 5V operation are essential. ## Where to Buy - [Arduino Store (US)](https://openhardware.directory/r?to=https%3A%2F%2Fstore-usa.arduino.cc%2Fproducts%2Fnano-every&ref=openhardware.directory&product=arduino-nano-every&source=md-export) — $10.50 - [Arduino Store (EU)](https://openhardware.directory/r?to=https%3A%2F%2Fstore.arduino.cc%2Fproducts%2Fnano-every&ref=openhardware.directory&product=arduino-nano-every&source=md-export) — €11.61 - [DigiKey](https://openhardware.directory/r?to=https%3A%2F%2Fwww.digikey.com%2Fen%2Fproducts%2Fdetail%2Farduino%2FABX00028%2F10238801&ref=openhardware.directory&product=arduino-nano-every&source=md-export) — $13.80 - [Mouser](https://openhardware.directory/r?to=https%3A%2F%2Fwww.mouser.com%2FProductDetail%2FArduino%2FABX00028&ref=openhardware.directory&product=arduino-nano-every&source=md-export) — $13.80 - [Amazon US](https://openhardware.directory/r?to=https%3A%2F%2Fwww.amazon.com%2Fdp%2FB07VX7MX27&ref=openhardware.directory&product=arduino-nano-every&source=md-export) — $14.00 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fstore.arduino.cc%2Fproducts%2Fnano-every&ref=openhardware.directory&product=arduino-nano-every&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Fdocs.arduino.cc%2Fhardware%2Fnano-every%2F&ref=openhardware.directory&product=arduino-nano-every&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fdocs.arduino.cc%2Fresources%2Fdatasheets%2FABX00028-datasheet.pdf&ref=openhardware.directory&product=arduino-nano-every&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Fdocs.arduino.cc%2Fresources%2Fschematics%2FABX00028-schematics.pdf&ref=openhardware.directory&product=arduino-nano-every&source=md-export) ## Tags `arduino`, `nano`, `atmega4809`, `5v`, `breadboard`, `compact` ## Images ![Arduino Nano Every](https://nbg1.your-objectstorage.com/openhardware-directory/entities/arduino-nano-every/691a9711f0e9.jpg) ![Arduino Nano Every](https://nbg1.your-objectstorage.com/openhardware-directory/entities/arduino-nano-every/24902aae2116.jpg) --- [View full device page](https://openhardware.directory/devices/arduino-nano-every)
