RS-485 vs CAN Bus

Developers should learn RS-485 when working on industrial automation, building control systems, or IoT projects that require reliable, long-range communication between multiple devices in noisy environments meets developers should learn can bus when working on embedded systems, automotive electronics, or industrial automation, as it's the standard for in-vehicle networks (e. Here's our take.

RS-485

Nice Pick

Developers should learn RS-485 when working on industrial automation, building control systems, or IoT projects that require reliable, long-range communication between multiple devices in noisy environments

Pros

• It's essential for implementing protocols like Modbus RTU or Profibus in manufacturing, HVAC, or energy management systems, where robustness and multi-drop capability are critical
• Related to: modbus, serial-communication

Cons

• Specific tradeoffs depend on your use case

CAN Bus

Developers should learn CAN Bus when working on embedded systems, automotive electronics, or industrial automation, as it's the standard for in-vehicle networks (e

• Related to: embedded-systems, automotive-engineering

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. RS-485 is a tool while CAN Bus is a protocol. We picked RS-485 based on overall popularity, but your choice depends on what you're building.

The Bottom Line

RS-485 wins

Based on overall popularity. RS-485 is more widely used, but CAN Bus excels in its own space.
