Why Do Embedded Developers Prefer UART Over SPI, I2C, or USRT for Debugging?

UART remains the go‑to debugging interface in embedded projects because it needs only three wires, works asynchronously, enjoys universal driver support, and benefits from decades of Unix‑style console tradition, whereas SPI and I2C were never designed for simple human‑machine interaction.
