Bus Interfaces
Overview
The LILYGO T-Connect Pro is an advanced industrial IoT platform consisting of three stacked circuit boards built around the ESP32-S3-R8 microcontroller. It combines long-range LoRa wireless (SX1262) with a comprehensive set of wired industrial interfaces — CAN bus, RS485, RS232, and W5500 Ethernet — plus a relay output for controlling external loads and DC power input for panel or DIN-rail mounting. An optional 222×480 LCD touchscreen provides local monitoring and control. With 16MB flash, 8MB PSRAM, WiFi, and Bluetooth 5 LE, the T-Connect Pro can bridge legacy industrial equipment to modern cloud platforms while simultaneously operating as a LoRa gateway. Available in 433, 868, 915, and 920 MHz LoRa frequency variants.
