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.
Update time: February 11, 2022

The L76K module boasts a multi-satellite positioning system supporting GPS, BeiDou, GLONASS, and QZSS.
It allows both multi-system joint positioning and single-system independent positioning, featuring AGNSS support.
Equipped with a built-in low-noise amplifier and surface filter, this module ensures fast, accurate, and high-performance GNSS positioning.
Compared to a single GPS system, the multi-satellite system significantly enhances the number of visible and usable satellites, improving positioning accuracy, even in complex urban environments.
The AGNSS function reduces first positioning time, and the built-in low-noise amplifier ensures high sensitivity and precision in signal capture and tracking, even under weak signal conditions.
The integrated surface acoustic filter enhances anti-interference ability, and the module includes an active antenna detection and protection circuit for durability.
The display features a 1.54-inch electronic paper display with a front light, offering 200×200 resolution for clear visibility even in dark environments.
