The Desk of Ladyada - Lets design a Pico to Arduino Shield converter

We got a user request today for a board that would convert a Raspberry Pi Pico $4 microcontroller board to use Arduino shields. An interesting idea! Let's go through what we do at the Desk when a new idea like this is presented to gauge feasibility. The Great Search - 5V eFuse https://www.digikey.com/short/b9c215hd eFuses are a nifty way to protect your electronics from over/under powering - handy for maker electronics AND industrial equipment that needs to keep chugging along no matter what happens to the power supply. We had someone ask us to design a board that would take 4xAA input and give USB output - one way to do that is with a buck-boost converter (which we already have) but maybe we could get away with a lower-cost and complexity design. Instead we'll look for an eFuse that will permit no more than about 5.5V and have reverse current, reverse voltage and under/over voltage protection!
