 Wait, that's not it. That's just a metro card. There we go. It is the Metro M4 Express One of my favorite development boards what we're talking about here is a really fast chip lots of memory So it's based on that Cortex M4 that's AMD 51 chip and it has a lot of great peripherals on it cases where I really love to reach for the M4 I'm at the start of a project. I may be not even sure what Board I'm going to use ultimately maybe not even sure what the form factor is But I just need to work out some of how things are going to be wired So I'll go with one of these Metro M4s and then in this case this was when I started working on that Pip Boy project I wanted to plug in the SPI wiring and Get this up and running on a board that I can plug things into I know it's going to have enough power to do pretty much Anything in circuit Python or in Arduino the product pick this week is the Metro M4 express
