Lilygo T-Echo Meshtastic

Description:Introducing the LILYGO® TTGO T-Echo, an advanced iteration of the LILYGO T-BEAM, tailored for seamless integration with Meshtastic. Prioritizing Bluetooth compatibility and low power consumption during its design, the T-Echo features the NRF52840 Advanced Bluetooth 5, Thread, and Zigbee multiprotocol SoC.
