By dedicating enough time and effort practicing and doing projects you will soon find yourself as a real embedded engineer! 😀
computer system that is part of a larger system and performs some of the requirements of that system. For example, a computer system used in an aircraft or rapid transit system.
The hardware and software of an embedded system are usually minimized and optimized for specific functions. The embedded system includes at least one microcontroller, microprocessor or digital signal processor. The embedded system designed to optimize reliability, cost, size and power saving for applications.
An embedded system is a computerized system that is purpose built for its application.
A physical system that employs computer control for a specific purpose, rather than for general-purpose computation, is referred to as an embedded system.
An embedded system is a system in which the computer (generally a microcontroller or microprocessor) is included as an integral part of the system.
Often, the computer is relatively invisible to the user, without obvious applications, files, or operating systems. Examples of products with invisible embedded systems are the controller that runs a microwave oven or the engine control system of a modern automobile.
A combination of computer hardware and software, and perhaps additional mechanical or other parts, designed to perform a dedicated function.
In some cases, embedded systems are part of a larger system or product, as in the case of an antilock braking system in a car.
The embedded systems engineering roadmap is structured into three fundamental areas: SOFTWARE, HARDWARE, and SOFT SKILLS.
While the intersection of hardware and software is prevalent in embedded systems, specific job titles tend to emphasize one aspect over the other. For instance, roles like "Embedded Software Engineer/Developer," "Firmware Engineer/Developer," and "Embedded Linux Engineer/Developer" predominantly focus on software development. In contrast, positions such as "Embedded Hardware Engineer" and "Hardware Design Engineer" primarily deal with hardware design and electronics. Moreover, there are roles like "Embedded Systems Engineer" that necessitate a comprehensive understanding of both hardware and software.
It's crucial to note that each company in the embedded industry may have unique requirements for a given job title. Therefore, it's essential to tailor your focus based on your career aspirations. If you're seeking an embedded software position, prioritize the software-related skills outlined in the roadmap. Conversely, if you're interested in an embedded hardware job, concentrate on hardware skills and dedicate more time to learning electronics.
The roadmap provides a comprehensive guide to the essential topics for a typical "Embedded Systems Engineer" role. By delving into both software and hardware aspects, you can develop the necessary skills to thrive in this dynamic field. However, if you have a clear preference for software or hardware, you can tailor your learning path accordingly.
Note
Remember that the importance of individual software and hardware skills can differ depending on the specific requirements of the company and the job role. [!TIP] To differentiate between the types of learning resources and the quality of their content, specific symbols are used before each item.
Resource types:
- 📘 : Books
- 🎞️ : Videos
- 📝 : Write-ups, articles, and blog posts
- 🔗 : Other links that do not fit into any of the above categories
Content quality symbols:
- 👶 : Easy-to-understand and beginner-friendly resources. Refer to them if you do not have prior knowledge in a topic.
- 💎 : Well-known references that have truly invaluable and comprehensive content. Refer to them if you want to deepen your understanding of a topic.
If you feel overwhelmed by the extensive list of topics in the roadmap, you're not alone. Before delving too deeply, let's ease into it with some simple starter projects. Learning embedded systems engineering takes time and effort. Don't get discouraged if you don't understand something right away. Keep practicing and you will eventually get there.
Engaging in hands-on projects is the most effective approach to learning. Rather than solely relying on theoretical knowledge from books or articles. Undertaking projects allows for practical learning experiences. Even a seemingly basic project has the potential to teach you more than hours of aimless reading. You can refer to books, articles, and courses when faced with difficulties in understanding the problems in real-world projects.
Don't try to build a complex project right away. Start with small, manageable projects to get your feet wet.

At first this was meant to be my personal reading list but as the list gradually became bigger and bigger, I wondered why not share it with others. So I did research on current job postings for embedded engineering roles, selecting the most frequent skills and including them on a roadmap. In order to make the roadmap more comprehensive I also added some basic skills and finally came up with what you see here.
The idea of creating this roadmap came from vazeri / Embedded-Engineering-RoadMap-2018 which was well designed but had some flaws and not updated for years. I took that idea, changed the structure of the roadmap and tried to improve it. The initial results can be accessed in m3y54m / Embedded-Engineering-Roadmap-Archived which is now archived. Early versions of the roadmap were created using Balsamiq Wireframes which is not suitable for these types of diagrams. So I decided to use Microsoft Visio instead and redrew the whole diagram.
