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

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.

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!

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.
