Stop wasting time on manual testing of embedded systems and start with robotic test automation.

FreeHIL is an open-source Hardware-in-the-Loop (HIL) infrastructure portable across all microcontrollers.

Build a HIL simulator using tools you already have on your desk—like standard evaluation boards.

If you are an embedded systems engineer, you know the pain: hours spent manually probing boards, checking signals, and repeating the same tests every time you change a single line of code.

In the world of Embedded Systems, Hardware-in-the-Loop (HIL) simulation and Test Automation with frameworks like Robot Framework are often seen as luxuries reserved for big-budget projects. But why?

I am launching FreeHIL to fill this gap.
