UART vs I2C vs SPI: ¿Cuál Protocolo Usar en tu Microcontrolador? (Guía Definitiva)

🔌 Choosing the right communication protocol can make or break your project! In this guide, we break down the three most important protocols in the world of microcontrollers: UART, I2C, and SPI. We explore how they work, their pros and cons, and when to use each one to ensure fast and efficient data transfer. Master the hardware behind the protocols! While these protocols handle the digital data, the physical signals rely on solid analog foundations. Check out my Master Pack to learn about signal integrity, filtering, and the analog design required for reliable communications. 🚀 MASTER PACK: The Analog Designer’s Path (48 Guides) The most complete technical library for professional electronics design. 🌎 Global Store (Gumroad): https://electrolabeducativa.gumroad.c... 📢 Note for International Students: The PDFs are in Spanish, but they feature universal schematics, formulas, and LTspice simulation files.
