Lilygo T-Echo Meshtastic

$76.99

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.

 

Description:Introducing the LILYGO® TTGO T-Echo, an advanced iteration of the LILYGO T-BEAM, tailored for seamless integration with Meshtastic. Prioritizing Bluetooth compatibility and low power consumption during its design, the T-Echo features the NRF52840 Advanced Bluetooth 5, Thread, and Zigbee multiprotocol SoC.

Building upon the functionality of the T-BEAM, the T-Echo retains the LORA capabilities with the LILYGO SX1262 version functional module. Leveraging the Semtech SX1262 LORA RF transceiver chip, it operates within the 868/915MHz ISM frequency band, boasting high stability with a TCXO 32MHz crystal oscillator. With a half-duplex transceiver module delivering up to +22dBm power and a receiving sensitivity of -139dBm, it ensures reliable long-distance wireless data transmission and reception.

Key Features:

  • Multi-satellite positioning system L76K, supporting GPS, BeiDou, GLONASS, and QZSS, enabling multi-system joint positioning and single system independent positioning.
  • AGNSS function for faster initial positioning, along with a built-in low-noise amplifier and surface filter for high sensitivity and precision positioning, even in weak signal conditions.
  • 1.54-inch electronic paper display with front light, offering 200×200 resolution for clear visibility even in dark environments.
