Baud Rate Estimator
Estimate UART baud rate from clock frequency, prescaler, and divider. Validate your communication accuracy and detect timing mismatches.
Baud Rate Estimator
Enter your system clock frequency (Hz), prescaler, and baud divider (UBRR). Optionally, enter a target baud to see the deviation percentage.
Communicate Accurately.
Validate your UART and serial configurations — ensure precise baud timing, minimal error, and reliable embedded communication across devices.
