LILYGO® TTGO 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 and SotfRF, 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, reception channel isolation, advanced LORA spread spectrum communication technology, strong anti-interference, and privacy can realize long-distance wireless data transmission and reception.

T-Echo Meshtastic

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 compact with GPS has a good battery life I’m impressed

Tasso Schille
perfect Flarm replacement

Together with an ogn registration works perfectly.

Robin Webb
Works as advertised

Plugged in, switched on, set up and away it goes

David Cooper
Very nice piece of hardware

Firstly I’d like to say that for the price, this is an absolutely fantastic device, and I’ve been genuinely impressed with all of the LilyGO products that I have tried so far.

The two things I wish this device would have however are a mini speaker or buzzer for SoftRF alerts, and WiFi capabilities. Otherwise it is in my view a perfect product.

Delivery was reasonably prompt and the buying process through the LilyGO website was seamless.

Fabien Campi
Fonctionne parfaitement

Testé en vol avec une application de suivi qui détecte les trafics flarms. Les indications du t-echo sont en accord avec l'application... sur laquelle je suis moi-même visible. Bref, un petit flarm totalement fonctionnel pour moins de 100€
