Mike is a Firmware Engineer at Golioth. His deep love of microcontrollers began in the early 2000s, growing from the desire to make more of the BEAM robotics he was building. During his 12 years at Hackaday (eight of them as Editor in Chief), he had a front-row seat for the growth of the industry, and was active in developing a number of custom electronic conference badges. When he's not reading data sheets he's busy as an orchestra musician in Madison, Wisconsin.

Use Zephyr SoC config files to streamline hardware types

Zephyr configuration that is specific to the chip, not just the board itself, can be centralized in your application. This means less duplication of configuration options across your IoT board definitions which improves both readability and maintainability of your code.
