Baud

While often used interchangeably in simple serial communication, they are technically distinct: : The number of symbols per second. Bit Rate (bps) : The number of bits per second.

: Higher rates (e.g., 115200+) are necessary for transferring large files or real-time sensor data. : In systems like CAN bus , specific

: In systems like CAN bus , specific rates like 500 kbps are standard for automotive networks. termios(3) - Linux manual page - man7.org Bit Rate : The most common "baseline" for

Common values used across hardware like Arduino and RS-232 include: : In systems like CAN bus

(symbol: Bd) is a unit of measurement for symbol rate in telecommunications, representing the number of signaling events (such as voltage or frequency changes) that occur per second . Core Concept: Baud vs. Bit Rate

: The most common "baseline" for low-speed, reliable communication.

: A standard high-speed setting for modern microcontrollers and console ports.
