I took the course during the Chuseok holiday with a strategy of listening through the entire content once, then repeatedly reviewing it. The overall course structure was well-organized with explanations and hands-on practice. It was very helpful for understanding motor control from a practical perspective. I hope that power conversion courses on BMS or inverters (ESS, UPS, etc.) will be offered in the future. Thank you for your hard work.

I'm currently job searching and feeling overwhelmed, but this lecture seems like it will be a great help. Usually in other lectures, when dealing with STM32, they use HAL drivers which made deep understanding difficult, but in this lecture, since you handle direct register settings based on datasheets, it seems possible to gain a deep understanding of MCUs. Also, the inverter design section was easy to understand as you explained the operating principles and selection of each component step by step. The buck converter design was also impressive. It was interesting to see that control theory applies to pure hardware design as well. Additionally, I only had a rough theoretical understanding of PI controllers before, but seeing you demonstrate how to tune P and I gains while looking at graphs during actual speed control made it much easier to understand, and I feel like I'm getting a sense of how to select P gain and I gain. Thank you so much for creating such a great lecture! (Oh, and I'm using the chatGPT you created well 😊😊)

Electric Kickboard Development Process Summary (Inside Embedded YouTube)

Why did I create this course?

During my university years, I took various courses beyond my major classes. While some were beneficial, most of them only covered simple feature implementation.

People around me always advised that if I wanted to improve my skills quickly, I should "work on projects." However, when I actually tried to start a project, the process itself—from selecting a topic to organizing the necessary knowledge and finding information—was not easy. Of course, I did grow through this process, but I always thought it would be better if unnecessary trial and error could be reduced.

So in this course, I've structured it so you can learn circuit design, STM32 firmware, and BLDC motor control as one connected flow.

Many courses on the market often focus on basic functions such as LED On/Off, PWM waveform generation, and button interrupt implementation using simple kits like Arduino or Nucleo boards.

While this type of learning is helpful at the beginner stage, I believe that the most effective way to build real skills as an embedded developer is to directly experience complete, well-rounded projects.


Have you had these concerns?

  • Circuits, firmware, PCB… Learning them separately means they don't connect in actual practice

  • I studied major subjects diligently, but the knowledge is fragmented and I can't grasp the overall flow

  • I'm preparing for employment or a job change, but I don't have any tangible results to prove in my portfolio

  • I want to do a project, but I don't know where or how to start

This course is different

You will experience the actual embedded development process as it is.

  • Hardware: Circuit design, component selection, 4-Layer PCB

  • Firmware: Direct STM32 register control, BLDC drive algorithm

  • Integrated Verification: Electric Kickboard Manufacturing & Driving Test

Deliverables: 36V/350W 3-phase inverter + BLDC motor control firmware + completed kick scooter
Materials provided: Schematics, PCB (Gerber), firmware source code, BOM 100% open
Support: Course-dedicated GPT + Q&A for close support until completion

Learn everything about embedded development
through hands-on design

Is just making a motor spin enough to complete a product?
Simple operation tests alone don't constitute real-world development experience.

"Making the motor spin" is just the beginning,
embedded developers design circuits, firmware, and systems in an integrated way.
•••

We build an actual rideable electric scooter and become real developers.

오뜨 소개페이지 배너_960300 (1)

Based on experience with actual projects including the global top 3 automakers, we've included only the core competencies needed in real-world practice.

✅ Real projects that work in the field

You will design and implement an actual rideable electric scooter. From requirements definition to circuit/firmware, you'll follow the same process as in real-world practice to create a high-quality final product.

✅ Exclusive GPTs provided for the course

We provide lecture-exclusive GPTs for students. You can ask questions about anything you're curious about during class to a GPT chatbot trained on the lecture content, enabling faster and more efficient learning.

✅ Complete Mastery of Hardware & Firmware Practical Skills

From 4-Layer PCB design to BLDC control algorithms and STM32 firmware, we cover all practical skills. Developers who understand both hardware and software together are stronger in the field.

✅ 100% provision of everything from schematics to source code

Schematics, PCB design files, and firmware source code all provided! Even students designing for the first time can follow along with the hands-on exercises and create high-quality results without trial and error.

To become a proper embedded developer,

Why do you need to know
both hardware and firmware?

In real development environments, problems don't simply occur in just one area.
An issue that seemed like it could be solved with a single firmware setting often turns out to originate from circuit design, and conversely, a phenomenon that appeared to be a hardware problem is frequently caused by firmware issues such as timing or sampling logic.

For example, in practice, these situations often occur:

1⃣ Motor vibration issue? → Thought it was a firmware setting, but it was PCB noise interference
2⃣ Board overheating issue? → Thought it was circuit design, but it was a firmware current setting error
3⃣ Sensor value spikes? → Thought it was hardware noise, but it was a sampling timing issue

Like this, what appears on the surface to be a problem with either firmware or hardware can only be accurately identified and quickly resolved by examining both sides. Ultimately, to improve product completeness, the ability to design and make decisions integrating both areas is essential.

Many companies already
require integrated capabilities.

Various companies are requiring integrated capabilities in both hardware and software (firmware) design.

You can learn things like this.

① Embedded development process that follows the actual workflow

You will experience the actual product development process used in the field, from requirements definition to HSI document creation, circuit design, and firmware. You will comprehensively cover 3-phase inverter circuit design, 4-Layer PCB implementation, and firmware logic, allowing you to learn the core embedded technologies that span the entire process from design to implementation.

② Learn the criteria for selecting appropriate circuit components and parts

You'll learn how to select and design appropriate circuit components based on product requirements, rather than simply listing parts. Additionally, focusing on key components such as MCU, MOSFET, Gate Driver, Buck Converter, and NTC, you'll master how to choose and design components that fit your objectives.

③ Practical PCB Design Know-how

You'll learn design methods that consider actual current flow and noise characteristics, not just simple wiring. You'll develop PCB design capabilities that can be immediately applied in practice, including high-current design, critical signal routing, and ground separation.

④ STM32F7 MCU Firmware: Learning Through Direct Control Without HAL

By directly controlling the registers of the STM32F767 to build firmware, you can gain a deep understanding of the MCU's internal structure and operating principles, going beyond simple API usage. By analyzing configuration items based on the MCU manufacturer's reference manual and implementing them in code, you will significantly elevate your firmware skills.

    https://smartstore.naver.com/inside_embedded/products/12165875635

  • You can manufacture and use the board yourself using the provided schematics and PCB files without purchasing the kit.

  • However, you will need to separately purchase accessories such as the throttle, 3-phase & hall sensor windings, UART module, ST-Link v2, and connectors in addition to the board.

🤷‍♂ Is it possible for non-majors and beginners?

  • If you have some knowledge of circuit theory and electronic circuits, it's possible.

  • Among current students, there are some who are from liberal arts backgrounds but are following the course well.

  • If you get stuck along the way, we'll help you resolve it through dedicated GPTs and community Q&A posts.

❓Do I have to use an in-wheel motor?

  • Building an electric scooter requires a significant additional investment.

  • Just the 36V battery, kickboard, and motor alone cost over 400,000 won.

  • For those who find the cost burdensome, we have designed an inverter that allows practice with a 24V small BLDC motor.

  • The BLDC motor driving method is the same for both in-wheel motors and small motors, so they can be driven using the same firmware.

  • The detailed information is explained in the course introduction video and blog.
