Look at what the antenna does.


LILYGO®TTGO T-Echo is a version evolved from LILYGO T-BEAM. At the beginning of the design, more consideration was to adapting to Meshtastic.
so Bluetooth and low-power consumption were considered when designing, and NRF52840 Advanced  Bluetooth 5 was selected thread and Zigbee multiprotocol SoC. 
The LORA function continues T-BEAM's LILYGO SX1262 version functional module.


T-SX1262 wireless transceiver module, using Semtech SX1262 LORA RF transceiver chip design, working in the 868/915MHz ISM frequency band, integrated high stability TCXO 32MHz crystal oscillator, half-duplex transceiver module, power up to +22dBm, receiving sensitivity -139dBm. Automatic transceiver Switching, internal transmission, and reception channel isolation, advanced LORA spread spectrum communication technology, strong anti-interference, and privacy can realize long-distance wireless data

Battery capacity: 850mAh

Application scenarios:

- DIY creation    - LoRa networking   - GPS positioning   - IOT terminal control - Stem education product

Features of the module:

Multi-satellite positioning system L76K is a support multi-satellite system (GPS, BeiDou, GLONASS, QZSS), multi-system joint positioning, and single system independent positioning, support AGNSS function, built-in low noise amplifier, and surface filter, can provide users GNSS module with fast, accurate and high-performance positioning experience.

Compared with a single GPS system, the high-precision positioning multi-satellite system greatly increases the number of visible and usable satellites, improves positioning accuracy, and can achieve stable high-precision positioning even in complex urban environments.

It supports the AGNSS function, which can greatly Reduce the time for the first positioning, built-in low-noise amplifier, can achieve high sensitivity, high-precision positioning, and fast signal capture and tracking, even under weak signal conditions can also ensure a good positioning performance, built-in surface acoustic filter, can greatly The anti-interference ability of the module is enhanced, and the active antenna detection circuit and protection circuit are integrated inside to protect the module and the active antenna from damage.

The display uses a 1.54-inch electronic paper display with front light, 200x200 resolution 1.54 front LED E-paper, and it can be used in a dark environment.

Not bad...

As far as mestastic itself and the device is very nice. The packaging has be a bit worried. I dropped it one time from about 2.5 feet and it hit on the bottom button and broke off inside the device. I took it apart and the button was floating around inside. Haven't fixed up a replacement for the button yet. My thought was to buy a few of these for my kids and use on camping trips where there is no Cell service. But being so fragile I have to rethink my decision. Again as far as mestastic goes it is a great device. Would have given 5 starts but the build quality has me worried.

Thank you for your feedback, we already have a solution for the button issue, we will contact you via email, please check your inbox later.

Amazing bit of electronics.

The whole thing is polished and easy to use. Erasing, reflashing and rebooting is easy and straightforward. Excellent bit of kit.
