Week06. Electronics Design
1. Assignment and Result
About the process, I made new page and made links are below, because the long page makes me confuse.
| GROUP ASSIGNMENT | THE RESULT |
|---|---|
| - use the test equipment in your lab to observe the operation of a microcontroller circuit board | Process -> Kitakagaya: Week6 Electronics Design - My work: Use the oscilloscope RIGOL DS1054 to observe the operation of Seeed Studio XIAO RP2040 and micro:bit |
| INDIVIDUAL ASSIGNMENT | THE RESULT |
|---|---|
| - design a development board to interact and communicate with an embedded microcontroller |
PROCESS -> Kicad - Design my own main board of final project, using Kicad and Seeed Studio XIAO ESP32C3. - Check the datasheet of Seeed Studio XIAO ESP32C3 |
| - extra credit: try another design workflow | - |
| - extra credit: make a case for it | - |
| - extra credit: simulate its operation | - |
2. Prototype1: Main Board for Final Project
- I draw the prototype1 of Main board for my final Project. The process of Kicad is here.
2-1) Schematic
2-2) Board design / HEROSHOT
2-3) BOM
| Parts | Quantity | reference |
|---|---|---|
| Seeed Studio XIAO ESP32C3 | 1 | - |
| PinHeader_1x04_P2.54mm_Vertical_SMD | 2 | for LCD & RFID2 module |
| PinHeader_1x02_P2.54mm_Vertical_SMD | 1 | for Power |
| Resistor 0ohm | 2 | for instead of Jamper |
2-4) Pinout of Seeed Studio XIAO ESP32C3
The Pinout and component overview in link.
2-5) pull up resistor for SDA and SCL
There is a pull-up resistor built into the RFID2 module. For the LCD (AE-AQM1602A_KIT), it also had a jumper pad to enable the pull-up resistor, and I did it to be enable. Therefore, I did not need pull-up resistors for these two I2C devices on the board circuit.

- RFID module (old version)
-
RFID2 compared to the previous generation RFID UNIT only makes the replacement of read and write IC (RC522->WS1850S), there is no difference in function.

3. My Thought
- I think that Electronics Design is one of the most difficult tasks that required a lot of effort, because I had to look up datasheets, and find out which electronic components should be used and look for the circuit is correct.
- In my case, it took a very long time to be able to design electronic board.
- Below is my note, to looked for the electronic parts during Pre-study.
- I knew that I need pre-study before FabAcademy, so I started learning from last August 2022. First, I looked and search the rule of electrical parts with the 2022 Electronics Design class page. Then, I watched the video of class to learn more, but I have many thing that I didn't understand. I search again on websites, it was annoy time to find beginner level site that I can understand. During learning, muRata- Electronic Components site(Japanese) helps me a lot.
- As I was researching, I saw videos of them short-circuiting, which also scared me.
- After that, I learned the basics of electronic circuits and Kicad at a e-leaning site (udemy) and took on this Fab Academy, but I am still struggling with electrical design. I need more study for electronics design. I hope I can get used to do it, and continue enjoy this work.
- I had never used an oscilloscope before, so I learned a lot about the procedure and how to use it through group work for the first time. I still need to learn more to be able to use the oscilloscope.
