Arduino Pro Mini – Compact ATmega328P Microcontroller Board (5V, 16MHz)

The Arduino Pro Mini is a tiny yet powerful microcontroller board based on the ATmega328P chip. Designed for projects where space is limited, it offers all the core Arduino functionality in a small form factor, making it ideal for embedded applications, wearables, mini-robots, and low-power devices.

Unlike larger Arduino boards, the Pro Mini does not include a USB interface; programming is done via an external USB-to-serial adapter, giving the board a more compact design and lower power consumption.
