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.

Very nice product!

Well made and work perfectly. Only wish the nodes were cleared before shipping. They were hard to clear.

Some assembly and firmware issues from manufacturing/testing but support fixed it

The adhesive holding the pouch cell to the assembly came loose after shipping and the battery was flapping around in 1/2 units I purchased. The GPS antenna was unstuck from its position in the enclosure in the other unit. Easy to open up and reattach both.

There were meshtastic nodes already in the persistent memory of both devices I received, with locations in Hong Kong. Normal firmware deletion and reflashing of Meshtastic does not delete these nodes. This is frustrating because each node generates its own page on the display which you have to scroll through. After emailing lilygo support a few times they provided me with a firmware to wipe all nodes stored in persistent memory. Once done, reflashing with meshtastic left me with a clean setup and I could re-add my own nodes.

Overall, I'd recommend.

Great device, nicely integrated

Bought two and have been impressed with their performance and the eink display. Unlike my T-Beams, I don’t have to worey about missing messages because they are always powered. Tested the antennas with a VNA and they are surprisingly broadband and resonant. My only gripe is lack of a button lockout switch, which would present them from coming out of sleep when buttons are accidentally pushed. Otherwise, this is a great device!
