The most popular and widely used micro controller on the planet. The Arduino Uno is a great board for beginners, small projects, and those on a budget while offering the same great experience and quality of the Arduino line up.
While not used for many 3D printer controllers, the board is popular amongst Creality 3d printer owners for flashing firmware onto their machines. If your Creality printer does not have a bootloader enabled controller, you’ll need an Arduino Uno to update your firmware.
