LILYGO® & Meshtastic T-Echo:
- A evolved version of LILYGO T-BEAM, T-Echo is designed with a focus on Meshtastic compatibility, featuring Bluetooth and low power consumption.
- It utilizes the NRF52840 SoC, supporting Bluetooth 5 / Threads / Zigbee multi-protocol.
- The LORA function, inherited from T-BEAM, uses the LILYGO SX1262 version functional module with a Semtech SX1262 LORA RF transceiver chip.
- Operating in the 433/868/915MHz ISM frequency band, it integrates a high stability TCXO 32MHz crystal oscillator, ensuring half-duplex transceiver functionality with a power of up to +22dBm and receiving sensitivity of -139dBm.
- The module enables automatic transceiver switching, internal transmission and reception channel isolation, and employs advanced LORA spread spectrum communication technology for robust anti-interference and privacy. This facilitates long-distance wireless data transmission and reception.
Upgrade Content:
- Upgraded from the fragile 3D printed shell to a more durable ABS material enclosure, aligning better with the product's positioning.
- Color options have expanded to include white, black, gray, and brown, offering greater variety.

L76K Module Features:
- The L76K module boasts a multi-satellite positioning system supporting GPS, BeiDou, GLONASS, and QZSS.
- It allows both multi-system joint positioning and single-system independent positioning, featuring AGNSS support.
- Equipped with a built-in low-noise amplifier and surface filter, this module ensures fast, accurate, and high-performance GNSS positioning.
- Compared to a single GPS system, the multi-satellite system significantly enhances the number of visible and usable satellites, improving positioning accuracy, even in complex urban environments.
- The AGNSS function reduces first positioning time, and the built-in low-noise amplifier ensures high sensitivity and precision in signal capture and tracking, even under weak signal conditions.
- The integrated surface acoustic filter enhances anti-interference ability, and the module includes an active antenna detection and protection circuit for durability.
The display features a 1.54-inch electronic paper display with a front light, offering 200x200 resolution for clear visibility even in dark environments.

it’s good just need to be updated great comunicatuon tool. using power bank to charge UT up draws 2 watts of power when charging.
Jaqueline Phipps –
Not so fast delivery. Well packaged, and even box with pinout graph. Device is awesome. Everything is made with quality. Looks very good and works well with my Heltec V3. I haven’t had the chance to test the NFC, but it looks like it’s not used in such devices yet. I’ll recommend it.
Chae Jiang –
Just as described. Working really nice. Up to 48hr on default battery. Plenty space on default enclosure for a bigger battery.
Benoît Cortot –
Very effective device, which really allows to communicate, at great distance. Very well made with gigantic autonomy.
Starr Lheureux –
Getting it setup so far so good
Susann Masson –
Everything except the quality of the stock antenna was excellent. Very satisfied overall.
Kholmatzhon Daniarov –
Legit and work great. NOW MAKE MORE AND YOU WILL SELL THEM ALL!
Dieter Krist –
As described. Came with Meshtastic preinstalled, and it’s 915 for US frequency as I ordered it. Shipping took about 3 weeks.
Lanie Edwin –
Both lilygo t-echos showed up and worked right away with zero issues. At the time (6/24) it was hard to find these units. Thank you

Good product. As expected
Zoraida Swick –
Will not work after a couple of days of use. Device won’t reset and won’t read via USB tether for any diagnostics
Kemberly Roza –
I ordered the items. They took ages to come. It turned out that the sellers did not provide information for customs. So therefore I ended up paying customs twice, once through Ali express and upon receiving the package. And ali express dismissed the case even after I provided the dockumentation. Not recommended

Very good quality, works well for my use case. Great device for a portable Meshtastic setup and included aerial works well
Lakisha Mullenix –
1. I ordered shipping by another shipping company, sent by mail.
2. The buttons on the case are just so-so, you have to press several times to respond, you have to get used to it.
3. updated the firmware, the developers of meshtastic have changed everything in the operation of this device for the sake of homemade products, and the backlight is no longer turned on.
4. I don’t know how to roll back, any older firmware does not help, return the functionality.
5. The seller does not respond to messages.
6. After a series of firmware, they simply turn off after a few minutes of work, or rather just freeze.
I do not recommend this device for purchase, if you still bought it, do not flash.

bought two of these. great little device. the antena is not very good, and I changed out with a 1/2 wave whip with an SWR of 1.22:1, which did the trick. the original antenna still works, but i wanted a better range due to my location. i like the built-in display, which is a bit small, but i like the paper white format. put it down to a 60 year olds eyesight.
the buttons standing proud of the case are a problem if you want it in a pocket or something, but i have it on my desk, so there are no issues.
package came quick. packed well in plastic cases and well worth the cost. i do recommend these if you don’t want to use some custom case with a Rok product.

Very fast and impeccable delivery. Very good product. Thank you. Thank you.
Kawano Tanyu –
Great product that can be made even better with minor upgrades (antenna, battery and extended case back). Fast shipping from vendor.
Jannette Wilmes –
Capped quickly and well, worked without problems. Runs for several days on one battery charge, even with an active GPS. E-Ink Diplay is easy to read, a background light can be switched on if necessary.
Meshtastic was pre-installed, but it is very easy to update without in-depth knowledge.
Good ready-made solution for Meshtastic for those who do not want to handicrafts themselves who want a mobile & compact device. I am very satisfied!
Savannah Brotherton –
Absolutely happy with my T-echo and the shipping. highly recommend this product and the seller.
Niam Mullins –
Very quick shipping, in the EU under 10 days. Device itself is awesome. Included antenna is not tuned to 868Mhz (more like to 915), even if it has a sticker on it according to VNA, but performs well enough until you get a better one.
Finn Junkermann –
I give the maximum rating because everything works, T-Echo delivered as described, but… The goods bear the hallmarks of use. After launch, I was shown Chinese nod-y (several dozen!). It was possible to indicate that it is used or tested and not issued as new (not unpacked).
Miriam Perry –
Quite happy, though it did arrive with an old firmware from before the meshtastic project redefined some of the buttons. Simple enough to update and a quick search later reveals backlight toggle is now press button 2 4 times.
Alfredo Lamanna –
I purchased five T-Echos. One of them doesn’t work. The others are great. Reached out to the store to organise a replacement and anticipate they will get back to me in the next day or so to resolve. Really happy with the speed of delivery. Just a bit disappointed they didn’t all work on arrival.
Liberatore Accordino –
great as described
Craig Piro –
Works great,very satisfied!
Nour Hartman –
I love how simple and portable this device is. However, the stock, although compact, is very badly performing, so I highly recommend replacing it ASAP.
