An elegant, powerful, and versatile control board for experts and beginners alike

The amomii UNO is a powerful development board for makers, hobbyists, and anyone looking to bring their projects to life. Based on the popular Arduino UNO, our board offers all the features and capabilities of the original, but with some key changes.

The amomii UNO is a microcontroller board, which means it's a small computer that can be programmed to control a wide range of devices and systems. With 14 digital input/output pins, 6 analog inputs, and a 16 MHz ceramic resonator, the board has everything you need to get started on your next project.

The USB-C port in place of the standard USB port used on other variations of the UNO microcontroller means the amomii UNO delivers faster data transfer, more effective power delivery, and a user-friendly reversible plug orientation. With the combination of this and other power handling enhancements, the board is capable of handling an impressive 1.5 at 5V, a three-fold increase compared to the original Arduino UNO's power handling of 500mA.

On top of this, for the more advanced users, the amomii UNO has auxiliary ports which can be soldered to for UART and I2C connections, and additional 5V and Gnd pins.

Whether you're a seasoned maker or new to the world of microcontrollers, with its sleek style, easy-to-use design and powerful capabilities, the amomii UNO is the perfect choice for your next project.

Learning coding and electronics is a valuable and in-demand skill, and the amomii UNO provides an exciting and practical way to gain hands-on experience.

Programming is done on the Arduino Integrated Development Environment (IDE) using the C++ programming language. C++ is a powerful and widely-used programming language that has many applications in areas such as robotics, game development, software engineering, and scientific research. Learning C++ can provide a strong foundation for understanding programming concepts and can lead to further exploration in the field of computer science.

In educational settings, the amomii UNO can be used to teach STEAM (Science, Technology, Engineering, Arts, and Math) concepts in a fun and engaging way. The coding textbook included with the UNO was written by our founder Shaun Armstrong, who has 10 years of experience as a STEAM department head. The amomii UNO is also a great tool for personal projects and experimentation, allowing you to explore your creativity and innovation.

Overall, the amomii UNO is an excellent way to gain practical skills and knowledge while having fun. Whether you're a beginner or an experienced maker, the amomii UNO provides endless opportunities for learning and experimentation, making it a valuable addition to any educational or personal toolkit.
