I’m Shawn Hymel, an embedded systems engineer with a passion for teaching. Over the past decade, I’ve worked with DigiKey, Microsoft, Hackster, and Edge Impulse to create technical content that connects. I’ve helped thousands of learners get started with STM32, understand the ESP-IDF, dive into Zephyr, and much more.
My goal is simple: help you learn the skills that actually make a difference in the embedded world.
