At this point, I’m aware of 3 different ESP32 + LoRa mesh projects.
Likely through some unfortunate non-magic of non-coincidence, all three projects have selected different primary development boards.
I do have 2 Pycom LoPy4 boards, and got a mesh going in a couple minites. But that project is kind of outside the scope of my question because they’re more or less developing the software to run on their hardware – ostensibly to sell more of their own hardware.
What I’m wondering is what might be the best medium-term purchase options for those of us wanting to experiment with as many projects as possible. The SX127x chipsets most of the LoRa boards run are already fairly dated (circa 2013?). The new chipsets don’t appear to be in many boards yet. But since the instruction sets are different, there will likely be some compatibility issues at some point.
The new chipsets are in the newer Heltec CubeCell ($11.90 at the time of writing w/o oled or SMA).
I also see that the manufacturer of the Meshtastic supported T-Beam, LilyGo, is officially supporting the disaster.radio hardware on their v2.1 1.6 board (w/o oled)
At this point, the main question in my vague rambling is something along the lines of… what are your future plans for board support? Have you tested the Heltec CubeCell boards?
My other question is whether there is a board that others have successfully tested on disaster.radio and Meshtastic.
An ideal future scenario might be for LilyGo to work with Meshtastic and disaster.rario to release an updated T-Beam based on the newer SX126x chipsets. The LilyGo AliExpress listings advertise that they are open to that kind of partnership.
It’s great that we have several options at this point, but I’d rather buy 4 of the same boards I can use flexibly than a bunch of semi-inter-operable EOL randoms.
