The UNO Mini is a compact, fully functional version of the classic UNO-style development board. Designed for users who prefer a smaller footprint without sacrificing compatibility, this board maintains the familiar layout, pin functions, and microcontroller features of the traditional UNO.
Despite its size, the UNO Mini delivers the full performance of an ATmega328P-based board. It includes a USB-C connector, standard I/O pin availability, and a clean, modern PCB design suitable for both learning and professional prototyping.

Despite its size, the UNO Mini delivers the full performance of an ATmega328P-based board. It includes a USB-C connector, standard I/O pin availability, and a clean, modern PCB design suitable for both learning and professional prototyping.
This small-format board operates just like a standard UNO. It supports all typical UNO workflows, libraries, and shields (within physical sizing limits) and is ideal for compact projects, portable builds, classroom environments, and rapid prototyping.
The board is powered by the ATmega328P microcontroller and works with the popular Arduino IDE and most other AVR-compatible toolchains. Simply connect via USB-C, upload your program, and begin experimenting with sensors, modules, and electronic circuits.
