LILYGO T-ECHO BME280 Wireless Transceiver Module NRF52840 SX1262 LORA GPS 1.54" E-paper for Arduino

Product Description:

LILYGO T-Echo is a version evolved from LILYGO T-BEAM. At the beginning of the design, more consideration was given to fit for Meshtastic and SotfRF, so Bluetooth and low power consumption were considered in the design. It selected NRF52840 Advanced Bluetooth 5, Thread and Zigbee multi-protocol SoC.

T-SX1262 wireless transceiver module adopts SX1262 LORA RF transceiver chip for Semtech, working in the 868/915MHz ISM frequency band. It integrates high-stability 32MHz TCXO and half-duplex transceiver module, with power up to +22dBm and -139dBm receiving sensitivity.

Automatic transceiver switching, internal transmission and reception channel isolation, advanced LORA spread spectrum communication technology and strong anti-interference and privacy can help 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.
- 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 and 200x200 resolution 1.54" front LED E-paper, and it can be used in a dark environment.
