Embedded System blog​

Welcome to My Embedded Stuff! This is my personal blog about embedded systems, where I intend to share my knowledge, analyze current news, and review equipment and tools from the sector.

I also plan to publish articles about good design practices and comment on methods that have worked for me in my day to day life as an embedded systems engineer, with the goal of learning and enjoying this field.

My intention is to publish new posts weekly. And, of course, feel free to comment on anything you think is relevant in the posts, and don’t hesitate to write to me through my “contact” page with anything that comes to mind: suggestions, proposals, help, etc.

If you’d like to know more about me, I recommend visiting the “About” page to learn a bit more about who I am.
