Lilygo T-Echo Braun TTGO Meshtastic 868MHz

This is a LoRaWAN APRS Tracker from LilyGo. The T-Echo is an extension of the T-Beam series. The T-Echo features an L76K multi-system GNSS module, which measures position with an accuracy of 2 meters and subsequently transmits via an SX1262 LoRa transceiver. The integrated nRF52840 MCU offers Bluetooth 5.0, Bluetooth Mesh, Zigbee, and ANT connectivity. Additionally, it can communicate through all common interfaces such as UART, SPI, I2C, I2S, QSPI, TWI, and PDM. A 1.54-inch E-Paper display shows all necessary information with very low power consumption. Together with the integrated 850 mAh Li-Po battery, this allows for a significantly longer runtime compared to an OLED display. The module features an NFC sensor on the underside, which allows the E-Paper display to be conveniently updated with a mobile phone. The module is programmed via a USB-C port.
