About EmbedCalc

EmbedCalc is a small collection of free, no-signup calculators for problems that come up repeatedly in embedded systems, embedded Linux, and electronics work — things like UART baud rate error, devicetree memory region math, GPIO sysfs numbering, timer prescaler values, and CRC checksums.

It's built and maintained by Naman, an embedded Linux / Yocto engineer. The tools exist because they're the kind of quick sanity-check calculations that are easy to get wrong by hand and annoying to re-derive from scratch every time.

Every tool runs entirely in your browser — nothing you type is sent to a server or stored.
