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.
Thank you for sharing your feedback on the areas that were lacking. To provide some clarification via this comment: 1. An ESD protection diode is a component that limits the input voltage to a certain level to prevent the circuit from being damaged by high voltage from human hands, clothing, etc. Therefore, diodes are placed on a total of three lines: the 5V line and the two data lines. Since these diodes operate bidirectionally, their orientation does not matter. Additionally, because USB-C can be plugged in normally or flipped, either DN1/DN2 or DP1/DP2 will always be connected, so the diode only needs to be placed on one of them. 2. I am currently using the free program OBS Studio for recording, but there are issues where the window title at the top does not appear, and the menu window is not visible when selecting menus with the mouse. I probably need to become more familiar with how to use it or switch to a different program. For now, I plan to resolve the issue of invisible menus by capturing the screen separately and inserting it into the existing video. 3. The mouse click highlight is also something I need to find a solution for. Thank you for your valuable feedback. I will make sure to improve these points in the next lecture. I am glad to hear that this was the lecture you were looking for and that it was helpful. Sincerely, Greentam
