NULA Core

Looking to get started with electronics and Arduino projects, or searching for a reliable board for your next design? NULA Core is a compact, beginner-friendly yet powerful development board designed for makers of all skill levels. It is the direct successor to the well-known Dasduino CORE, featuring the same trusted hardware with updated labeling and a refreshed identity. If you’ve used older Croduino or Dasduino boards, you’ll feel right at home.

Despite its small footprint, NULA Core packs serious capability. Measuring just 63 × 22 mm, it offers 22 I/O pins (14 digital and 8 analog, with A6 and A7 analog-only), enough for the vast majority of projects. At its heart is the proven ATmega328 microcontroller, fully compatible with the Arduino ecosystem and programmable via the Arduino IDE. The board connects via USB Type-C, operates at 5 V, and includes a 3.3 V regulator.

NULA Core also integrates features that simplify portable and modern projects, including a Lithium-ion battery charger and connector, a qwiic connector for effortless I²C expansion, and both a standard pin 13 LED and a full-color WS2812 RGB LED. Available with no headers, male headers, or female headers, NULA Core adapts easily to breadboards, soldered projects, and enclosures alike.
