Learn how to build a digital twin of the STM32 Nucleo board using Zephyr OS and QEMU — no physical hardware required. Engineer Ari Mahpour walks you through creating a fully virtual PCB target, injecting signals into ADC channels, and reading back telemetry over serial, all running in emulation on your local machine. This approach is ideal for distributed embedded teams who need to develop and test firmware before boards return from fabrication.
Take your embedded testing workflow to the next level by reusing the same pytest integration test scripts across both virtual and physical targets. Ari demonstrates how to abstract your test infrastructure so that swapping a QEMU-based digital twin for a real Nucleo board requires minimal changes — making hardware-free CI testing a practical reality for any embedded project.
