LilyGo T-Echo TTGO Meshtastic 868MHz

This is a LoRaWAN APRS tracker from LilyGo. The T-Echo is a continuation of the T-Beam series. The T-Echo features an L76K multi-system GNSS module that measures the position within 2m accuracy and then sends it via an SX1262 LoRa transceiver. The integrated nRF52840 MCU offers Bluetooth 5.0, Bluetooth Mesh, Zigbee, and ANT connectivity. Moreover, it can communicate through all standard interfaces such as UART, SPI, I2C, I2S, QSPI, TWI and PDM. A 1.54-inch E-paper display shows you all the necessary information with very low power consumption. Together with the integrated 850mAh Li-Po battery, this allows for much longer runtimes compared to an OLED display. The module has an NFC sensor on the bottom, which allows you to comfortably refresh the E-paper display with your mobile phone, for example. The module is programmed via a USB-C port.
