    Core Specifications & Hardware Review

    • Chipset: ESP32-S3 Dual-Core (Wi-Fi / Bluetooth).
    • Industrial Interfaces: Integrated RS485, RS232, and CAN Bus support.
    • Connectivity: Ethernet module onboard for wired networking.
    • LoRa Module: Available with Semtech SX1262 or SX1276 (433/868/915/920 MHz).
    • Display: 2.33-inch LCD for real-time monitoring and diagnostics.
    • Dimensions: 88 * 60 * 72 mm.
    • Weight: 240g (Robust build for industrial environments).
    • Serial Variants: Different H761 versions for specific LoRa frequencies.

    The LILYGO T-Connect-Pro Review highlights a significant shift towards professional industrial automation. This board isn’t just a microcontroller; it’s a multi-protocol bridge that connects legacy industrial equipment (RS485/RS232) to modern IoT networks via LoRa and Ethernet.

    Features and benefits

    Why I love the T-Connect-Pro

    • Protocol Powerhouse: The inclusion of RS485, RS232, and CAN on a single ESP32-S3 board is rare and extremely useful for factory automation.
    • Visual Feedback: Having a 2.33-inch LCD allows developers to debug communication lines (like Modbus or CAN traffic) directly on the device without a laptop.
    • Wired Reliability: The onboard Ethernet ensures a stable connection in environments where Wi-Fi is congested or unavailable.
    Pros and Cons

    Strengths & Weaknesses: A Balanced Review

    What I Like

    • Complete Interface Suite: Simultaneous support for RS485, RS232, CAN, and Ethernet.
    • Industrial Form Factor: Designed to fit into control cabinets and withstand professional use.
    • ESP32-S3 Flexibility: Plenty of power for handling multiple communication protocols and encrypted data.

    Points to Consider

    • Learning Curve: Managing multiple hardware serials and the CAN bus requires advanced programming knowledge.
    • Bulkier Design: At 72mm depth, it requires more space than standard LilyGO development boards.

    Review Summary

    Early data from the official LilyGO store indicates strong professional interest:

    • Build Quality: Users praise the 240g weight and robust dimensions, noting it feels like serious industrial equipment rather than a hobbyist toy.
    • Communication: Technical buyers appreciate the variety of LoRa versions (SX1262 vs SX1276) to match existing infrastructure.
    • Documentation: As with most LilyGO Pro products, users recommend checking the GitHub repository for specific pinouts of the RS485 and CAN interfaces.

    Performance overview

    Detailed Overview: Performance Analysis

    This LILYGO T-Connect-Pro Review confirms the device as a reliable gateway. The ESP32-S3 chip handles the bridge between the CAN bus and Ethernet without latency issues, while the 2.33″ LCD provides an excellent interface for local status checks. The SX1262 LoRa module ensures that even remote industrial sensors can be integrated into the central control system.

    Applications and projects

    Practical Use Cases

    • Modbus Gateway: Converting RS485 Modbus RTU data to MQTT via Ethernet/Wi-Fi.
    • Automotive/Industrial CAN Bridge: Monitoring vehicle or machinery telemetry.
    • Remote Factory Monitoring: Using LoRa to transmit industrial data over long distances in large facilities.
