LilyGo T-Connect Pro ESP32-S3 868MHz LoRa with 2.8 inch TFT Display

The LilyGo T-Connect Pro ESP32-S3 module is a powerful industrial and IoT development board with extensive interfaces for communication, control, and visualization. It is based on the ESP32-S3-R8 microcontroller with 16 MB Flash and 8 MB PSRAM and offers a wide range of features including CAN bus, RS232, RS485, Ethernet (W5500), LoRa (868 MHz), a 10A relay, and a QWIIC interface. The integrated 2.8-inch TFT display (ST7796) with capacitive touch allows user-friendly operation directly on the device. The modular design in three levels with clearly defined interfaces and a stable M3 mounting frame is ideal for use in industrial applications such as automation, energy management, or remote monitoring. Power is supplied via USB-C with 5 V/500 mA. With the variety of protocols (UART, SPI, I2C) and the use of proven Arduino libraries, the board is particularly developer-friendly. The compact design and professional signal routing make the module an ideal platform for demanding embedded projects with real-time visualization.

Features:

• The powerful ESP32-S3-R8 microcontroller has 16 MB Flash and 8 MB PSRAM.
• A 2.8-inch TFT display (ST7796) with 222×480 pixels provides clear visualization directly on the device.
