Note: This item is 868mhz, T-Echo SoftRF with BME280 version.
The T-Echo is a version evolved from LILYGO T-BEAM.
At the beginning of the design, more consideration was to adapt to Meshtastic and SotfRF, so Bluetooth and low power consumption were considered when designing, and NRF52840 Advanced Bluetooth 5 was selected Thread and Zigbeemultiprotocol 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 868MHz 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.
- 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, 200x200 resolution 1.54 front LED E-paper, and it can be used in a dark environment.
