CAN Bus

Nice Pick

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

Pros

• g
• Related to: embedded-systems, automotive-engineering

Cons

• Specific tradeoffs depend on your use case

SPI

Pick SPI when you need raw throughput to a single fast peripheral -- flash chips, SD cards, TFT displays, ADCs -- where its full-duplex 1-50+ MHz link beats I2C's 3

Pros

• 4 Mbit/s ceiling
• Related to: arduino, raspberry-pi

Cons

• Specific tradeoffs depend on your use case

The Verdict

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

The Bottom Line

CAN Bus wins

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