If you’re new to the Raspberry Pi Pico, the first thing you need to know is how to set it up with some firmware – in this case installing MicroPython. All you’ll need is a host computer with internet connection, a micro USB cable and this simple step-by-step guide. Starting with the very first time you plug in your Pico, I’ll walk through each stage, with a clear explanation of exactly what to expect and what to do when things get a bit baffling – like why your files have disappeared and how to find them again and open them through Thonny.
** Thonny is pre-installed on my Raspberry Pi 3B. If you are on Windows or Mac you can get the IDE here: https://thonny.org/ ***
