Think of a device that doesn't yet exist, but should. This might mean that something similar exists, but has deficiencies, or is too expensive. Build it. You may find that learning with concrete goals in a real problem is more effective that with something you're disinterested in. The trick with this skillset is it's a combination of many related skills. The specifics will depend on the project. Some examples: Soldering Low-level language proficiency; generally C, C++, or Rust. Also includes interrupts, concurrency, DMA, atomics etc Embedded tooling (Pick your poison!) Part selection and BOM/cost management EDA software, including PCB layout, designing footprints, schematics etc Communications protocols Reading datasheets and manuals Familiarity with your MCUs peripherals of interest for the specific proj How you get the PCB ordered etc Mechanical skills, eg designing and building enclosures CAD software like Solidworks, Inventor, Fusion etc You'll probably need some combo of all of these, unless you're in/starting a company that has a division of duties. Good luck!
