 All right, Lady, what is this? It's 10 o'clock at night. Do you know where your hardware is? Well, you will when you have this RTK board. This is a precision GPS and real-time kinematics location shield that we've designed here. So I got two of them. I don't even talk about how expensive these are. So it was really stressful when I first plugged in the USB and I was like, I really hope it enumerates. But this actually has native USB. And I've got it connected here. I soldered on an SMA connector. And this is going to a U-blocks antenna that's out the window. Thankfully, the window isn't too far away from my desk. And you can see I've even got pulse per second RTK signal. And then what's interesting is that this just shows up as like a comport. And then over here I've got the U-blocks U-center. And you can see it's seeing satellites and data. So a really good start. Next up, I have to figure out how to connect one of these as base station to one of these as a rover and communicate between the two. I might use our new Metro S3 as the transport layer. So solder this on top and then use this either ESP now, perhaps, or Wi-Fi or Bluetooth low energy to transport the RTK data between the two. And then they can tell exactly how far apart they are. So just started like five minutes ago. Just pulled this in. But thankfully, we're off to a good start.
