LILYGO T-ETH LTE
Introduction
LILYGO T-ETH ELITE-LTE Shield is a 4G cellular network expansion module specifically designed for the T-ETH-Elite mainboard. It integrates LTE communication and L76K high-precision GPS positioning functions, enabling remote data transmission in areas without network coverage. This module is compatible with the T-PCIE LTE module and offers both T-PCIE mode (4.2V power supply) and official PCIE mode (3.3V power supply), providing flexible adaptation to various deployment needs. The built-in L76K GPS module enables accurate location tracking and time synchronization, making it suitable for logistics management, mobile device monitoring, and other scenarios.
With the 40-PIN GPIO interface (compatible with Raspberry Pi layout) and dedicated communication pins (such as MODEM_RX/TX), the module seamlessly integrates with the mainboard's Ethernet (W5500), Wi-Fi/Bluetooth, and PoE power supply (36~57V), forming an LTE+GPS+Ethernet multi-protocol hybrid communication hub. It supports development on platforms like Arduino and ESP-IDF, offering industrial-grade reliability and flexibility. This makes it an ideal solution for IoT nodes in remote areas, vehicle-mounted terminals, and industrial remote monitoring.
