Pro Mini

The Arduino Pro Mini is a compact, lightweight microcontroller board used for building electronic projects. It functions like a small computer that can be programmed to control devices such as sensors, LEDs, and motors. Designed for projects where space and power efficiency are important, it operates with low voltage and does not include a built-in USB port—requiring an external programmer for uploading code. Despite its size, it offers robust processing capabilities, making it suitable for embedded systems, wearable technology, and custom automation. Its simplicity and flexibility make it a popular choice among hobbyists and professionals for creating small, efficient electronic solutions.
