Error = actual − target; percentage = error ÷ target × 100. No chip compatibility guarantee.

A QUICK WALKTHROUGH

How to use this tool

  1. Enter the target baud rate and actual baud rate.
  2. Optionally record the reference clock used for your calculation.
  3. Calculate and review the error locally.

Explicit rate comparison

Error = actual baud − target baud; percentage error = error ÷ target baud × 100. Reference clock is recorded as context only.

GOOD TO KNOW

Common questions

Does this guarantee UART compatibility?

No. Framing, clock tolerance, sampling, wiring, and hardware documentation still matter.
