What's The Deal With Meshcore?

I've looked at Meshtastic in several videos, the off-grid radio text-messaging system. In this video I'm looking at another alternative that uses the same LoRa radio: MeshCore. I'm also testing out the Thinknode M9 messaging device from Elecrow. You can find it at the links below:

Update: As an FYI, I've been notified that some of the Thinknode M9 units inadvertently shipped with malware on the SD card. The company is notifying affected customers and replacing the affected batch, and future versions shouldn't have that issue. Here's the relevant bulletin: https://www.elecrow.com/Thinknode-M9-Security-Advisory-SD-Card-Malware-Risk.html
