LILYGO T-Echo Meshtastic 915MHz LoRa SX1262 Wireless Module NRF52840 GPS RTC NFC TTGO Development Board

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.

I got this because I’m interested in the mesh tastic idea and I wanted to try something out without having to build my own board and solder and everything else. I have the mesh tastic app on my phone. I somehow found this node. I tried sending messages to it, but I couldn’t seem to figure out how to read them. I have a lot more YouTube videos to watch and tutorials to learn about this more. I work with a physician who is into this type of technology and I told him about it and he is going to build his own board and we’re going to try to communicate.

This unit failed after 5 days in service. It has a puny 800mhr battery which does not give good run time. The supplied antenna is junk as reported on Meshtastic forums. You are better off with a Trekker 5 if you want a unit ready to go right out of the box.

I am a Ham (Extra Class), have an MSCS, worked in high tech, and LOVE this little device! If you enjoy cool new technology, then YOU will love it too - no matter what level you are at. Opened the box and found NO manual, but, on the small, high-contrast, 1.54" persistent black on white screen was "meshtastic.org". I visited the site and found a whole new world out there with amazing people and hardware that I previously did not know about. You should _not_ expect to just charge it up and start calling friends thousands of miles away, but you _can_ expect to have great fun while learning about "mesh" 2024 style. On YouTube, there are >= 2 excellent videos, created by some of my favorite Ham Radio YouTubers, devoted to emerging mesh technology and this _specific_ device. My rating of 5 Stars is because it is a powerful and relatively inexpensive way to dive into an amazing, state-of-the-art technology. BTW: One does NOT need to hold a Ham Radio license, or be an MSEE to work with mesh, BUT, if you are a Ham, you will have even more fun, and might remember APRS. I look forward to have fun working through this with a 16 year old friend who will have a great time - perhaps setting up a system for covertly messaging friends at school, or collecting qand disseminating weather data, or designing a neighborhood security system or... Enjoy!
