Overview

NULA Core​

Start building your next Arduino-based project with NULA Core, a compact yet fully featured development board designed for makers of all skill levels. With full Arduino IDE compatibility it brings the classic Arduino Uno experience in a much smaller and more project-friendly size.

Powered by the famous Atmel ATmega328P, NULA Core provides 22 I/O pins (14 digital + 8 analog), making it suitable for everything from simple electronics experiments to more advanced projects. Its built-in USB Type-C connector ensures easy programming and reliable power delivery.

Designed for modern and fast prototyping, NULA Core includes a Qwiic connector for effortless I²C expansion, an onboard 3.3 V regulator for powering sensors and breakouts, and a Li-Ion battery charger with connector for portable applications. It also features a WS2812B RGB LED, giving your projects an instant visual upgrade right out of the box.
