The LILYGO® T-Connect-Pro is a powerful and modular communication controller based on the ESP32-S3-R8 chip, equipped with 16MB Flash and 8MB (Octal SPI) PSRAM. Designed with a triple-layer PCB stack, it supports multiple industrial communication protocols, making it ideal for complex IoT and edge computing applications.

This board integrates CAN, RS485, and RS232 modules, enabling long-distance and industrial-grade communication. It also supports LoRa (SX1262) for low-power wide-area networking, and includes an Ethernet port (W5500) for stable wired connectivity. The 2.1" TFT LCD (222×480 resolution, ST7796 driver) and capacitive touch panel (CST226SE) offer an intuitive user interface.

Whether used for remote monitoring, automation control, or industrial networking, the T-Connect-Pro offers developers rich features in a compact and stackable form factor.
