Produktbeschreibung

Upgrade Content
Since the 3D printed shell is relatively fragile and does not meet the positioning of the product
So this time it is updated to an ABS material enclosure.
And three colors of black, gray and brown have been added.
Currently there are four colors of white, black, gray and brown.
Update time: 2022/2/11
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 adapt to Meshtastic and SoftRF, 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 transmission and reception.

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.
