I2C vs UART

Developers should learn I2C when working with embedded systems, IoT devices, or hardware projects that require communication between multiple integrated circuits on a single board, as it simplifies wiring and reduces pin count compared to parallel interfaces meets developers should learn uart for embedded systems and iot projects where low-cost, straightforward serial communication is needed between microcontrollers, sensors, or debugging tools like serial monitors. Here's our take.

I2C

Nice Pick

Developers should learn I2C when working with embedded systems, IoT devices, or hardware projects that require communication between multiple integrated circuits on a single board, as it simplifies wiring and reduces pin count compared to parallel interfaces

Pros

• It is ideal for scenarios where moderate data rates (typically up to 3
• Related to: spi, uart

Cons

• Specific tradeoffs depend on your use case

UART

Developers should learn UART for embedded systems and IoT projects where low-cost, straightforward serial communication is needed between microcontrollers, sensors, or debugging tools like serial monitors

Pros

• It is essential for tasks such as firmware debugging, data logging, and interfacing with legacy hardware due to its simplicity and widespread support in hardware like Arduino, Raspberry Pi, and ESP32
• Related to: embedded-systems, microcontrollers

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. I2C is a protocol while UART is a concept. We picked I2C based on overall popularity, but your choice depends on what you're building.

The Bottom Line

I2C wins

Based on overall popularity. I2C is more widely used, but UART excels in its own space.
