® TTGO Meshtastic T-Echo LoRa SX1262 Wireless Module 433/868/915MHz NRF52840 1.5

Product Description

LILYGO® & Meshtastic T-Echo:

• A evolved version of LILYGO T-BEAM, T-Echo is designed with a focus on Meshtastic compatibility, featuring Bluetooth and low power consumption.

• It utilizes the NRF52840 SoC, supporting Bluetooth 5 / Threads / Zigbee multi-protocol.

• The LORA function, inherited from T-BEAM, uses the LILYGO SX1262 version functional module with a Semtech SX1262 LORA RF transceiver chip.

• Operating in the 433/868/915MHz ISM frequency band, it integrates a high stability TCXO 32MHz crystal oscillator, ensuring half-duplex transceiver functionality with a power of up to +22dBm and receiving sensitivity of -139dBm.

• The module enables automatic transceiver switching, internal transmission and reception channel isolation, and employs advanced LORA spread spectrum communication technology for robust anti-interference and privacy. This facilitates long-distance wireless data transmission and reception.

Upgrade Content:

• Upgraded from the fragile 3D printed shell to a more durable ABS material enclosure, aligning better with the product's positioning.

• Color options have expanded to include white, black, gray, and brown, offering greater variety.
