T-Echo-Plus get it now
Overview
LILYGO T-Echo-Plus is an upgraded version of the T-Echo, designed with Meshtastic mesh networking in mind. It is powered by the Nordic nRF52840 MCU with Bluetooth 5.0 and NFC, paired with a Semtech SX1262 LoRa transceiver (433/868/915 MHz). The board features a 1.54-inch e-ink display, L76K GNSS receiver, BHI260AP intelligent sensor hub (IMU), a buzzer, and a vibration motor — making it ideal for off-grid communication, asset tracking, and portable Meshtastic nodes.
