 A little jewelry box. Hey, look, there it is. It is the Pi UART USB console and power add-on. Connects right onto these first headers of the Raspberry Pi. Fit that on there and just press down. So I'm plugging in USB-C there. And then I'm going to flick on the power switch. What I'll do is connect to it using a screen. So I'll type in my username, password, which it's going to tell you I haven't changed it. Now you can do things from here like adjust configurations. Maybe this is a headless setup. Let's say edit the config. And there we go. We can go in with Nano here, go maybe uncomment some of the overscan stuff for HDMI. If you're having HDMI issues, it might be impossible to see it on the plugged-in monitor, but you could go in here and make your changes. This is the Pi UART. It is a console and power add-on for Raspberry Pi.
