Rookie questions regarding #meshtastic: I'm thinking about getting a unit to mess around with, but feel a bit overwhelmed. I hear about Heltec as simple and inexpensive starter devices, (1) are these only for chat type of applications (that's what I seem to see in vids)? Today I listened to a podcast talking about LoRa and how it may be able to mesh web pages as well, at least some point. (2) Is LoRa the same thing as the Heltec devices? And (3) could you point me to a for-rookies resource or two that won't make my head spin?

I can dig around but thought asking for tried-and-true resources might save me some time.
