New Product - Two Channel Isolated RS485 Expansion HAT for Raspberry Pi

We're excited to introduce the Two Channel Isolated RS485 Expansion HAT for Raspberry Pi — a powerful addition to your Raspberry Pi toolkit that opens up industrial communication possibilities.

RS485 is a robust serial communication standard widely used in industrial automation, building control systems, and data acquisition applications. It excels in noisy environments and over longer distances compared to standard serial connections. Our new HAT brings this industrial-grade capability directly to your Raspberry Pi projects.

What Makes This HAT Special

The isolation feature is a game-changer for applications where electrical noise or ground potential differences could damage your Raspberry Pi. The two-channel design gives you flexibility to communicate with multiple RS485 devices simultaneously or create redundant communication paths for critical systems.

Whether you're building a home automation system, monitoring environmental sensors across a property, or integrating with legacy industrial equipment, this HAT provides the connectivity you need with the protection your Raspberry Pi deserves.

Easy Integration

Installation is straightforward — simply attach the HAT to your Raspberry Pi's GPIO header. The expansion board handles all the complex signal conditioning and isolation, so you can focus on your application logic rather than hardware troubleshooting.

With proper software libraries and clear documentation, you'll be communicating over RS485 in no time. The isolated design means you can confidently connect to external systems without worrying about voltage spikes or ground loops damaging your board.

Perfect For

  • Industrial IoT projects and remote monitoring
  • Building automation and HVAC control systems
  • Environmental data collection across multiple locations
  • Legacy equipment integration and modernisation
  • Educational projects exploring industrial protocols
