LoRa EBYTE E220-900T30D

The core chipset is not LW compatible.

And that module is point to point LoRa over a serial port only, so can’t run a LW stack.

Possibly useful as a key chain dangly bit.

If you want to launch a balloon and send telemetry, perhaps you could ask on one of the HAB forums, as you’d really be better off using a combination of UKHAS LoRa and HorusBinary v2 or the new v3, so you can tap in to the radio amateur network for receiving without any particular limits on how much data you send, unlike LW on TTN.

I know this combo works, I can even do it by remote control by using the @stevencellist tele-presence system. Latency can be a bit harsh, but it resulted in a successful flight last week even if the driving was a bit out of the way. My bad, I must learn the road network of other countries.

NB: We ONLY discuss LW on TTN/TTI here. Everything else is off topic, so please take the pointers above to do some serious Googling.
