T-Echo SoftRF NRF52840 LoRa SX1262 433/868/915MHz Wireless Module L76K GPS 1.54 E-Paper BME280 Sensor for Arduino
- Description
TTGO T-Echo Introduce:
1. LILYGO® TTGO T-Echo is a version evolved from LILYGO T-BEAM.
2. At the beginning of the design, more consideration was to adapt to Meshtastic and SoftRF, so Bluetooth and low power consumption were considered when designing, and NRF52840 Advanced Bluetooth 5 was selected Thread and Zigbe multiprotocol SoC.
3. The LORA function continues T-BEAM's LILYGO SX1262 version functional module.
4. 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.
