How Electronic Devices Communicate
Electronic devices rely on communication protocols to send and receive data. UART only uses two wires, but transfers data relatively slowly. SPI has faster data transfer, but it uses four wires. I2C is faster than UART and only uses two wires, so it’s a popular compromise. Take a look at the tutorials below to learn more!
Basics of UART Communication
UART is used to connect modules like GPS, Bluetooth, and RFID card readers to the Raspberry Pi, Arduino, and other microcontrollers. Learn how it works with this easy to understand tutorial.
Basics of the I2C Communication Protocol
The I2C communication protocol combines the best features of SPI and UART. This guide will show you how it works in an easy to understand format.
Basics of the SPI Communication Protocol
SPI is a communication protocol used to interface a variety of sensors and modules to microcontrollers. This easy to understand guide will explain how it works.
