I2C Protocol vs SPI

Developers should learn I2C when working on embedded systems, IoT devices, or hardware projects that require communication between multiple integrated circuits on the same printed circuit board (PCB) meets 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. Here's our take.

I2C Protocol

Nice Pick

Developers should learn I2C when working on embedded systems, IoT devices, or hardware projects that require communication between multiple integrated circuits on the same printed circuit board (PCB)

Pros

• It is particularly useful for connecting low-speed peripherals such as temperature sensors, accelerometers, LCD displays, and real-time clocks to microcontrollers like Arduino, Raspberry Pi, or ESP32, as it minimizes wiring complexity and supports multiple devices on a single bus
• Related to: embedded-systems, serial-communication

Cons

• Specific tradeoffs depend on your use case

SPI

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

The Verdict

Use I2C Protocol if: You want it is particularly useful for connecting low-speed peripherals such as temperature sensors, accelerometers, lcd displays, and real-time clocks to microcontrollers like arduino, raspberry pi, or esp32, as it minimizes wiring complexity and supports multiple devices on a single bus and can live with specific tradeoffs depend on your use case.

Use SPI if: You prioritize it is particularly useful in applications like reading data from sensors (e over what I2C Protocol offers.

The Bottom Line

I2C Protocol wins

Developers should learn I2C when working on embedded systems, IoT devices, or hardware projects that require communication between multiple integrated circuits on the same printed circuit board (PCB)
