Are you familiar with connecting ESP32 development boards and sensor modules using jumper wires, but feel overwhelmed and unsure where to start when it comes to creating your own PCB?
Or, are you familiar with Arduino but want to use a higher-performance microprocessor and wireless communication features?
There is plenty of information on the internet regarding ESP32 circuits, how to use KiCad, and how to order PCBs. However, it is difficult to find the entire process in one place—from configuring power and USB communication circuits to connecting sensors, wiring the PCB, and completing the actual manufacturing files and firmware.
In this course, you will follow a pre-completed ESP32 sensor board project and experience the following processes firsthand.
Understanding ESP32 basic circuits and key pins
USB-C power and 5V→3.3V power circuit design
Configuring a firmware download circuit using CH340
Connecting temperature/humidity/illuminance sensors, buttons, and LEDs
KiCad schematic design and component library management
4-layer PCB component placement and routing
DRC check and manufacturing file generation
Ordering from a PCB manufacturer
Writing firmware to operate the completed board
External communication using BLE and Wi-Fi
By the end of this course, you will go beyond simply using ESP32 development boards and will be able to understand and modify PCBs that incorporate the sensors and functions you desire.
Additionally, the KiCad projects and step-by-step firmware provided in the lecture can be reused as a starting point for creating environmental sensors, smart home devices, educational boards, robots, and IoT prototypes in the future.
The purpose of this course is not simply to deliver knowledge to you, but to give you the confidence that ""I am someone who can actually implement my ideas, I am someone who can create products.""
Those who have used Arduino and ESP32 development boards but are new to PCB design
Those who want to organize a project made with jumper wires into a single board
Those who want to learn KiCad through an actual ESP32 project
Makers who want to develop sensor-based products or educational kits
Software developers who want to understand both hardware and firmware together
Prospective entrepreneurs who want to create their own IoT prototypes
Those who only want to learn ESP32 coding without circuit and PCB design
Those who only want cloud server or Android app development
Experienced hardware engineers looking for high-speed digital circuits or industrial mass-production designs
When the lecture ends, you won't just be left with a record of having watched the videos.
You will be left with editable KiCad projects, manufacturable PCB designs, component libraries, step-by-step firmware, and ESP32 circuit design experience that can be reused in future projects.
Go from being someone who uses development boards to someone who designs their own boards.

In an era overflowing with digital content created by generative AI,
what is your competitive edge?
AI creates code, writes text, and generates images.
However, it cannot yet create data from the physical world on its own.
Filling this gap is the technology that connects AI with reality,
the Internet of Things (IoT).
Data collected through sensors is
not just simple information, but
a differentiated competitive advantage that only you can possess.
This course helps you become a creator who generates data,
rather than just a user following along in the
AI era.
This course is a practice-oriented lecture where you will design and produce your own custom development boards using the ESP32, a representative IoT microcontroller.
We have lowered the tuition barrier so that even beginners can learn easily. Invest just 6 hours.
Arduino users can transition directly to ESP32 development without any sense of unfamiliarity. (Using the Arduino development environment)
Beyond simply using ESP32 hardware,
you will experience the entire process from circuit design using KiCad to PCB fabrication, firmware writing, and hands-on practice,
developing the ability to integrally understand hardware + software..
The lecture covers the following core technologies:
Building an Embedded System
Digital input/output (GPIO) via buttons and LEDs
Analog input and sensor data processing
PWM control (analog output)
EEPROM data storage (non-volatile memory)
I2C Communication (Sensor Operation)
BLE communication (communication with mobile phones)
WiFi communication (Internet connection, Internet of Things)
This course is not simply about learning the ESP32.
This is the starting point for you to
transition from being a “person who uses AI”
to a “person who supplies data to AI.”
I had been following others' ESP8266 projects, but I wanted to create a professional single PCB layout from a breadboard circuit just like they do. So, I was studying bits and pieces from foreign websites and YouTube. Right around that time, this course was uploaded to Inflearn, and since it perfectly matched my goals, I decided to take it. Before taking the class, I wanted to learn the following: 1. Basic setup for drawing schematics 2. How to design circuits 3. How to use KiCad 4. How to use BLE and WiFi on the ESP32 While points 1, 2, and 3 are available on YouTube, the information was often fragmented. I felt this course would help me build a solid foundation in a condensed manner. Regarding point 4, I wanted to learn it because I had failed in the past after blindly installing various libraries for BLE and WiFi without understanding the basics. The advantages I felt after taking the course are as follows: 1. It's in Korean. This is a huge advantage. 2. I gained the confidence to try making a PCB myself. 3. The flow of learning is natural as it connects everything from circuit design to firmware. 4. Using EEPROM to store/change WiFi SSIDs was a fresh idea I hadn't considered before. 5. It was not difficult to follow along. On the other hand, here are some points I found slightly lacking: 1. There was a part about connecting three diodes for ESD protection, but I was curious about why three were used and why they were only connected in one direction; however, there was no explanation for that. 2. This is a minor point, but the title bars of program windows or sub-windows were not visible, which felt a bit stifling at times. 3. I wish there was a highlight on the mouse cursor when clicking. I don't think there were any major drawbacks. However, I think someone with absolutely no foundation and only curiosity might need to watch it several times to fully grasp the content. In conclusion, I believe there is no other course as convenient and easy to follow as this one, provided you have the will. I look forward to follow-up lectures. Thank you.
I took this course because I wanted to study embedded systems again after a long time. Since the course follows a hands-on practice approach, it helped me a lot in getting back into the swing of things. I am looking forward to the next lecture, and it would be great if you could cover some more advanced topics. Thank you.
I started with absolutely zero prior knowledge of electronic circuits or Arduino. Here are my thoughts after taking the course: 1. This is a condensed course that allows you to quickly build an MVP model with Arduino. I highly recommend it to those who want to create something with Arduino fast. 2. I once sent an email with an inquiry, and the instructor's feedback was both fast and detailed. 3. The lecture uses KiCAD 9.0, but downloading KiCAD now gives you version 10.0. This doesn't cause any major issues during development. 4. The overall audio quality of the videos is a bit low. 5. Even if you have zero prior knowledge of electronic circuits, it is perfectly fine to take the course while looking up unfamiliar concepts using GPT. 6. When accessing the Discord community URL via the "News" section, it says the invitation is invalid. 7. You can check the instructor's GitHub to see exactly what you will be learning before watching the lectures. Overall, this was a huge help. Thank you! Please make the next course soon!!
While studying MCU, I was always curious about how to manufacture PCBs, so I decided to take this course. You explained everything in an easy-to-understand way, which made my studies very comfortable.
I didn't have any basics and only had a vague curiosity, but it was good to be able to learn the fundamentals and various other things. When right-clicking the mouse or selecting the top menu, it wasn't captured in the video recording... so I could only tell by listening to the sound. It was a bit difficult trying to follow along blindly without knowing. I downloaded the latest KiCad and it was version 10.0... So I re-downloaded version 9.0 to follow the lecture. They seemed a bit different... it was hard to follow without knowing the details.
