T-ETH Elite LTE Shield

Overview

T-ETH Elite LTE Shield is a 4G cellular expansion board designed for the T-ETH-Elite mainboard. Integrates LTE communication and L76K GPS positioning, enabling remote data transmission in areas without Wi-Fi or Ethernet coverage. Compatible with T-PCIE LTE modules (T-PCIE mode: 4.2 V; official PCIE mode: 3.3 V). Combined with the T-ETH-Elite's W5500 Ethernet and PoE (36–57 V), forms an LTE + GPS + Ethernet multi-protocol hybrid hub. Suitable for industrial remote monitoring, vehicle-mounted terminals, and IoT nodes in remote areas.
