Supplier's note

  1. Three Technical Breakthroughs:

    • RS232 Protocol Compatibility: Ensures seamless integration with legacy systems, reducing retrofitting costs.
    • High-Relay Density: The Pro Model’s 16 SPDT relays enable control of complex multi-circuit systems, such as industrial automation grids.
    • Jumper Customization: Allows users to reprogram functions without hardware changes, ideal for prototyping or field adjustments.

  2. Optimal Version Selection:

    • Base Model: Best for basic smart lock applications (e.g., residential door locks) where cost efficiency is prioritized.
    • Advanced Model: Suitable for commercial settings (e.g., office access control) needing enhanced durability (IP65) and faster processing.
    • Pro Model: Designed for industrial environments (e.g., factory equipment control) requiring extreme durability (IP67), UL certification, and high relay capacity.

With the Pro Model’s IP67 rating, you can deploy the board in outdoor or wet environments while maintaining reliable operation. Pair its 16 relays with the RS232 protocol to automate complex systems like HVAC controls or security gates. The Advanced Model’s 115 MHz processor ensures smooth real-time monitoring in smart buildings, while the Base Model’s cost-effective design suits budget-conscious home automation projects.
