LilyGo T-Echo Brown TTGO Meshtastic 868MHz

This is a LoRaWAN APRS Tracker by LilyGo. The T-Echo is a continuation of the T-Beam series. The T-Echo features a L76K multi-system GNSS module which measures the position with 2m accuracy and then sends it via an SX1262 LoRa transceiver. The integrated nRF52840 MCU provides Bluetooth 5.0, Bluetooth Mesh, Zigbee and ANT connectivity. Moreover, communication can be done via 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 850mAh Li-Po battery, this allows for a much longer runtime compared to an OLED display. The module has an NFC sensor on the underside, with which you can conveniently refresh the E-Paper display with your phone for example. The module is programmed via a USB-C port.
