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

Love it, nice and portable works well! Paper white screen is nice and battery life fair.

Worked as intended, out of box I got about 1000ft of range with stock antennas. Like many others have stated, SWR is not great, so pick up some higher gain, better rated antenna when you get yours. I got two devices when I ordered mine and both had the same outcome during testing, so it wasn't just a one off.

This is a good starter for someone new to a mesh network, if you need more communication I would go with the pal pilot ones, came as advertised and had details of all parts on box, comes pre built.

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.

While the metastatic idea itself is very cool and works per well for its intended purposes, the build quality and longevity of this particular device isn’t very good. I’ve had my device ~6 months and it quit working, nor will it charge any more…now outside of Amazon return window, overall not really impressed

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!

I've purchased a couple of these and re-flashed the firmware using Liam Cottles' online RNode Flasher utility. They work very well as Reticulum Mesh Network RNode devices. I have one tethered to a Pi Computer via USB and another paired via Bluetooth to an Android phone running the Sideband chat program. Very reliable connectivity between these devices and other RNode devices.

Prodotto realizzato con molta cura e, a mio parere, molto bello anche esteticamente. Essendo "appassionato" di elettronica ho controllato anche all'interno e ho trovato tutto sistemato con cura. All'interno c'è una batteria 3.7 Volt da 850 mAh. Era già pronto per la prima configurazione in quanto aveva già il firmware Meshtastic precaricato. Ho quindi verificato l'antenna in dotazione con il NanoVNA e purtroppo devo dire che l'antenna è bella esteticamente, funzionante si, ma la resa è un po' bassa. Quindi consiglio di abbinare un'antenna 868 MHz (869,525 MHz è la frequenza operativa che ho impostato nella configurazione con il preset Medium Fast) diversa da quella in dotazione. Molto comodo e preciso il GPS, così come il tasto touch superiore che illumina il display paper Ink molto bello. Con una piccola spesa cambio l'antenna e poi è tutto al top. Con antenna più performante avrei dato 5 stelle

Great LoRa device for Meshtastic and the like. The signal reception properties of it are very good, even with the stock antenna provided. Its compact form makes it very portable. Needs recharding each few days, even with GPS positioning turned off, though.

Great way to get introduced to Meshtastic. Internal gps and temp sensor was a surprise. Small antenna works amazingly well. Slightly different firmware menu than my other V3 Heltastic.

Der LILYGO T-Echo mit SX1262-Modul hat mich positiv überrascht. Trotz der kompakten Bauform bietet er eine gute Funkreichweite und eine stabile Verbindung – ideal für Meshtastic. Das integrierte GPS arbeitet präzise. Das E-Paper-Display ist klar ablesbar, selbst in direktem Sonnenlicht, und verbraucht kaum Energie. Der Akku hält dank des sparsamen LoRa-Betriebs lange, und das Gerät lässt sich bequem über USB-C aufladen. Besonders gefällt mir, dass die Firmware-Updates und Konfiguration über die Community gut dokumentiert sind. Für Bastler und Outdoor-Enthusiasten ist das T-Echo eine großartige Lösung, sei es zur Positionsübertragung, im Mesh-Netzwerk oder für eigene IoT-Projekte. Fazit: Ein vielseitiges, robustes und leichtes LoRa-Gerät mit GPS – perfekt für Meshtastic, Tracking und Experimente mit großer Reichweite.

ADDENDUM: The device didn't last 2 days, basically the lower button is no longer working making the device unusable. Returned for refund. ----------------------- I'm still trying to understand what can be the real purpose of this device, it does the job but it is so badly documented that it is causing more confusion than anything else. In fact the device is well built, good casing and an e-paper display that allegedly should make the battery last longer than an LCD display however the battery is so undersized (800mA) that it won't last that long anyways. The producer website is proposing 3 different firmware, Meshtastic, SoftRF and LilyGo Stock without explaining the differences between them causing the real confusion. When you try to use it with Meshtastic the display is basically useless because the settings and functionalities are requiring a cellphone, either Android or iPhone, with a dedicated (free) app hence you won't have any kind of useful information on the device itself. I tried both the other two firmware, LilyGo Stock and SoftRF and I could not find any purpose or joy in using them. The thermometer and the hygrometer embedded are just a joke because the values will be for the device and not for the environment so don't spend extra money for those, which are also using more of the battery making the lifespan shorter. Would I recommend? Not really unless you see a purpose for it, if you want to experiment then buy a T-Beam version with GPS integration for half of the price.
