CONNECT WHAT YOU ALREADY KNOW
Embedded skills grow
through complete projects.
A job often covers just one part of development. Circuit and STM32 lessons give you useful pieces. Here, you connect them in one motor-control project. You learn why each design decision matters and put it into practice.
Essential theory: circuits, devices, motors, feedback and PI control.
Extensive practice: component selection, schematics, PCB layout, STM32 registers, motor commutation and tuning on real hardware.
Extensive practice: component selection, schematics, PCB layout, STM32 registers, motor commutation and tuning on real hardware.

Modules 1 through 5 are included at launch. Modules 6 through 8 are scheduled for November 15, 2026. English audio and English captions are included for all 63 launch lessons. Modules 1 through 5 list the individual video lessons. Modules 6 through 8 show the planned topics.
BEFORE YOU ENROLL
Know what to prepare.
Know what is included.
Your development setup.
- A Windows or macOS computer with internet access and a USB connection for the programmer.
- STM32CubeIDE for C firmware, building and debugging.
- EasyEDA for schematic capture and PCB layout.
For comfortable study, we recommend 8 GB RAM or more, an SSD and a 1920 × 1080 display. These are course recommendations, not tested minimum specifications. Check the current tool requirements for your operating system and processor before installing.
Files you can build from.
- At launch: two lecture PDFs totaling 409 pages, with 276 pages of circuit and motor-control material and 133 pages of STM32 material.
- At launch: a ZIP of eight STM32 examples, also available through Free Downloads.
- With the follow-up release: additional lecture notes, bringing the full PDF collection to 500+ pages, and motor-control source code.
- With the follow-up release: a bill of materials (BOM), schematics, PCB Gerber files and a JLCPCB fabrication guide.
Both releases are included with course access. The remaining files accompany modules 6 through 8, scheduled for November 15, 2026. The STM32 example archive contains the same eight examples offered as free resources.
Build your own controller board.
The follow-up release includes Gerber files, a JLCPCB fabrication guide and a BOM for making your own board. Wait for those files before ordering parts. A physical kit is not included in the course price.
Budget separately for the PCB and components, a compatible BLDC motor and power supply, an ST-Link programmer, a UART adapter, connectors and wiring. Check the hardware guide before ordering parts.
The main design is a 36V / 350W three-phase inverter. The PI exercise uses a compact 24V BLDC motor. International kit sales and shipping are not currently offered on this site.
Basic C and circuit theory.
You do not need an engineering degree. You should be comfortable with basic C programming and circuit theory. That foundation is enough to follow the course and work through the exercises.
If both subjects are entirely new to you, this course will be challenging. Start with the fundamentals before taking on a complete motor controller. You can try the free STM32 materials first.
Prior motor-control experience is helpful, but it is not a prerequisite.
This is a motor-controller design course. You will connect circuit design, PCB layout, firmware and control on the same piece of hardware.
A good fit if you write firmware and want to understand the circuit you drive, or you design hardware and want to know what the firmware needs from it.

BEFORE YOU BEGIN
A few practical details.
Why not just watch the free videos?+
The YouTube lessons explain one concept at a time. This course follows one board from the first requirement to a measured speed response: parts, schematic, 4-layer layout, firmware and tuning, in order. You also get the lecture PDFs. Course Q&A is open to everyone, and I answer the questions there myself. With the November 15 release, the course adds the motor-control source code, schematics, a BOM, Gerber files and a JLCPCB guide.
What is included at launch?+
The launch release contains 63 video lessons, totaling approximately 13 hours 42 minutes. Modules 1 through 5 cover circuit fundamentals, motors and control, inverter design, PCB principles, and 10 STM32 register-level labs. It also includes two PDFs totaling 409 pages and an archive of eight STM32 examples already offered as free resources. English audio and English captions are included for all 63 launch lessons. Enrollment is open.
When will the remaining project lessons arrive?+
Modules 6 through 8 are scheduled for November 15, 2026: EasyEDA schematic and PCB practice, BLDC firmware, and PI speed control. The complete course is expected to total approximately 20 hours. Both releases and their included materials are covered by the early-bird price.
What hardware do I need?+
Hardware is purchased separately. A BOM, schematics, PCB Gerber files and a JLCPCB fabrication guide arrive with the follow-up release so you can make your own board. Wait for the hardware guide and check compatible motors, power supplies, programmers, wiring and accessories before purchasing parts. A physical kit is not included.
Can I use a compact motor?+
Yes. The PI exercise uses a compact 24V BLDC motor. The main hardware design project is a 36V / 350W three-phase inverter.
How does early-bird pricing work?+
The early-bird price is a one-time payment of $245 before applicable taxes. It ends on November 15, 2026 at 23:59 UTC; after that, the course is $350. It includes 63 lessons totaling approximately 13 hours 42 minutes at launch, the remaining project lessons scheduled for November 15, 2026, and lifetime access to the complete course. The full course is expected to total approximately 20 hours. No additional payment is required for the second release. Hardware is purchased separately.
ASK BEFORE YOU ENROLL
A question you might share.
Ask about the course, prerequisites or hardware. Approved questions and instructor replies are visible to everyone, so you can check what has already been answered.
I have education in mechanical engineering, and have thought of taking this course due to poor job market. I was wondering if there are prerequisites to this BLDC Motor Control course? We had Circuits 1 as part of my education. And I have done some programming in Matlab/ Simulink.
Polezero · Instructor
Hi, thanks for asking. Circuits 1 gives you a useful starting point. A basic understanding of circuit theory and electronics will make the course easier to follow, but you don't need to have designed a motor controller before.
I start with the components themselves: resistors, capacitors, inductors, diodes, BJTs and MOSFETs. The course then covers power-supply circuits and works through the controller hardware in detail, including MCU peripheral circuits, a buck converter and a three-phase inverter. So there are explanations of the parts and circuits before we move into the full controller project.
For the STM32 lessons, you'll also need basic C programming. Your MATLAB/Simulink experience is useful, but the firmware is written in C, so I'd suggest reviewing the basic syntax if you haven't used it before.
If you get stuck on a circuit or a piece of code, please ask me here or by email. I'll be happy to explain it in more detail. You may need to revisit a few fundamentals along the way, but you already have some relevant background to build on. The free resistor and buck-converter previews on this page are a good way to see whether the explanations suit you.
A course purchase is not required to ask.
