Arduino Nano Every – Compact ATmega4809 Development Board

The Arduino Nano Every is the evolution of the classic Arduino Nano, designed to deliver more memory, higher performance, and a lower price point while maintaining the same small form factor. Built around the ATmega4809 microcontroller, it offers a balance of simplicity and power, making it an excellent choice for everyday projects, education, prototyping, and DIY electronics.

With 48 KB of Flash, 6 KB SRAM, and a faster 20 MHz clock speed, the Nano Every outperforms the original Nano in memory and speed. It provides familiar connectivity with UART, SPI, and I²C interfaces, as well as 5 PWM pins and 8 analog inputs for versatile control.

Despite its compact size (45 × 18 mm, only 5 g with headers), it remains breadboard-friendly and plug-and-play with the Arduino IDE.
