Just chips, or on a board?

There's a tutorial linked from this page:

PS:
Note that "LoRa" is just an RF modulation scheme.
You can use just LoRa to connect 2 devices together - see the "peer-to-peer" examples.
LoRaWAN uses LoRa modulation, and adds a whole lot more to make a complete network system
You can't just connect two LoRaWAN devices together - they have to go via (a) gateway(s) and Network Server.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
