T-Echo Meshtastic 915MHz LoRa Development Board | SX1262 , NRF52840, GPS, TTGO

Super cool mesh radios! Not the smallest but work well and the screens are crisp. Would but again

Nice form factor and good rx/tx. I really dislike the buttons though. They are too easy to press by mistake or in a backpack/pocket. The buttons should be recessed and not protrude outside the case side.

Integrates with phone well, great addition to personal network.

meshtasic firmware works, what am i to say?

Full disclosure: two weeks ago I didn't know what Meshtastic was and had never even heard of LoRa. That being said, I'm having an absolute blast learning how to use these things, and I'm increasingly impressed by everything they can do. There are tons of resources online to help you get started, which is good because there's essentially no documentation included. I literally had to ask Google how to turn the thing on and off. Once you install the Meshtastic app, discover the mysteries of the power button, and figure out the basics, though, it's reasonably intuitive. Battery life has been impressive. I'm getting around 22 hours with moderate use, which is plenty for what I'm doing with them. Texting through Meshtastic is easy, and location sharing adds another whole level of usefulness. ATAK integration is also possible, although that's considerably farther down the rabbit hole and comes with a bit of a learning curve. Range is going to depend heavily on your antenna, terrain, settings, and where the units are located, so I'm not going to throw out some ridiculous mileage claim based on limited testing. The biggest problem I've had with these is that the more I learn about what Meshtastic and LoRa can do, the more of them I want to buy. Two weeks ago I didn't know any of this existed. Now I'm looking at antennas, solar-powered relay nodes, and wondering where else I could put one. Be warned: apparently they're contagious.
