Note:This item is 868mhz, TEcho SoftRF with BME280 version.
The TEcho is a version evolved from LILYGO TBEAM.
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 TBEAM’s LILYGO SX1262 version functional module.
TSX1262 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, halfduplex 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 antiinterference and privacy, can realize longdistance wireless data transmission and reception.
Features of the module:
Multisatellite positioning system L76K is a support multisatellite system (GPS, BeiDou, GLONASS, QZSS), multisystem joint positioning and single system independent positioning, support AGNSS function, builtin low noise amplifier and surface filter, can provide users GNSS module with fast, accurate and highperformance positioning experience.
Compared with a single GPS system, the highprecision positioning multisatellite system greatly increases the number of visible and usable satellites, improves positioning accuracy, and can achieve stable highprecision positioning even in complex urban environments.
It supports the AGNSS function, which can greatly Reduce the time for the first positioning, builtin lownoise amplifier, can achieve high sensitivity, highprecision positioning and fast signal capture and tracking, even under weak signal conditions can also ensure a good positioning performance, builtin surface acoustic filter, can greatly The antiinterference 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 1.54inch electronic paper display with front light, 200×200 resolution 1.54 front LED Epaper, and it can be used in a dark environment.
