LILYGO® TTGO Meshtastic T-Echo Introduce:


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.

Great

So far, so good. Limited number of users here in USA. A few contacts. Using this as a mobile device.

Great starter device for Meshtastic

Works out of the box, preflashed with Meshtastic firmware. Pair with your phone and get onto the mesh within minutes. Nice battery life, about 5 days with GPS disabled. Good maker community for changing batteries and 3D printing cases to fit larget batteries.

The epaper is nice. Refresh is a bit slow, but to be expected with epaper.

The antenna works, maybe 2-300 m in urban area, and 2-3 km line of sight. You'll want to buy a better antenna from Linx or Taoglas to get reliable connections.

There is an LED in the case behind the battery which cannot be disabled, and wastes battery power. This is a known design flaw. You can desolder it yourself, but really Lilygo should not populate that LED.

The reset button is on the side of the device and is easily pushed when it's in your pocket or backpack. The reset really should be in a pinhole on the rear of the case so you use eg a toothpick to reset the device, and the buttons on the side should be used as UI input (like page up/down)

Overall happy, and good little device to know whether you want to get further into Meshtastic. Would buy again.

Awesome for getting started

Perfect for a new user. Perfectly complements existing nodes as well. I also have a RAK solar node.

Good, but fragile

I bought two and 1 works well. The other one smoked on the second day. I dismantled it and see that the chip burned up.

For me the purchase was a pleasure. I would also like a second device. Unfortunately currently sold out. but I still have hope of buying a second one...
