LILYGO®TTGO T-Echo SoftRF Meshtastic BME280 TEMP Pressure Sensor NRF52840 SX1262 433/868/915MHz Module LORA 154 E-Paper
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 868 915MHz 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 Note Be sure to confirm the model to avoid misunderstandings T Echo SoftRF is the basic version You can choose the Meshtastic or BME280 version as needed 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
