I think the devices may be getting delivered, since they have ran out of the 880 (iirc?) boards .
Of course it may be another Kickstarter thing.
I'm somehow involved with a local LoRa (LoRaWAN) for our local city. We have a few competing lora solution up now.
A commercial one (though will have community free access hopefully) and hopefully our open platform based around TTN.
So I've rapidly been swatting up on it.
I have everything but LoRa up and running, our sensors are there (Pi's are not the best for this unfortunately as they use to much power, but I still use them for anything I have access to.
The ESP32, Lora, OLED things are much better and come pretty much complete, bar adding sensors, now for not a lot of money.
I do have some modules I'm going to wire up to a Zero though. Just need a bit of piece and quiet time to do it.
I'm using this for reference
