SPI vs UART

Developers should learn SPI when working on embedded systems, IoT devices, or hardware projects that require fast, efficient communication between a microcontroller and multiple peripherals 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.

SPI

Nice Pick

Developers should learn SPI when working on embedded systems, IoT devices, or hardware projects that require fast, efficient communication between a microcontroller and multiple peripherals

Pros

• It is particularly useful in applications like reading data from sensors (e
• Related to: embedded-systems, microcontrollers

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. SPI is a protocol while UART is a concept. We picked SPI based on overall popularity, but your choice depends on what you're building.

The Bottom Line

SPI wins

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