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 has a L76K multi-system GNSS module which measures the position to an accuracy of 2m and then transmits it via a SX1262 LoRa transceiver. The integrated nRF52840 MCU offers Bluetooth 5.0, Bluetooth Mesh, Zigbee and ANT connectivity. In addition, it can communicate via all common 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 enables a much longer runtime compared to an OLED display. The module has an NFC sensor on the underside, which you can use to conveniently refresh the e-paper display with your mobile phone, for example. The module is programmed via a USB-C port.
