 We are testing out some new feathers here. This is our RP 2040 bones board, RP 2040 basic with USB-C buttons, eight megabytes of flash. And in the space left over, we've got an RFM69 module. This could also be a Lora WAN module. Sorry, a Lora module that can run Lora WAN stack on the RP 2040. But this is just a plain RFM69. We've got a spot for a wire antenna, a UFL antenna connector. So it's good for connecting larger antennas, a semi-QT. And I've got another one over here. And if you back up a little bit, you'll see when I press the button on one, it appears on the other one. So hold on, I'll flip this over. And then I press the button on here. It sends the message over. So they're communicating with each other. And I also get the signal strength, which is a good way for me to test that my antennas are working. So all are good. Next up, I'm going to try Lora.
