The Raspberry Pi Pico is an entirely new type of microcontroller from Raspberry Pi. Small, cheap and flexible – it’s great for learning to code with MicroPython! Whether you’re looking to learn about the MicroPython programming language, take your first steps in physical computing or want to build a hardware project, the Raspberry Pi Pico – and its amazing community – will support you every step of the way. The Pico isn’t designed to replace the Raspberry Pi, which is a different class of device known as a single-board computer. Whereas you might use your Raspberry Pi to play games, write stories and browse the web, your Raspberry Pi Pico is designed for physical computing projects where it can control familiar components such as LEDs, buttons, sensors, motors and even other microcontrollers. The Pico can be quickly and easily programmed
