ELECTRONICS DESIGN

This week, I learned how to use Eagle in Fusion 360 to design a PCB board.

I started from learning a board Neil provided and tried to redraw the schematic of it. During this process, I checked the datasheet of D11C MCU to figure out the meaning of the pins. After that, I added an LED and a switch to digital pins respectively. During the design of PDB board, I added 4 o ohm resistances to corss the lines, which is not elegent. I need to learn how to design a 2-layer board next time.

As for manufacuring, the shop is crowded this week, and when I got a chance to mill, I found out the setting from week-02 doesn't work. The mill cannot penetrate the copper layer. I spent some time adjusting the cyt depth and found out 0.01 inch works now instead of 0.004 inch two weeks ago. However, when I am going to mill the outline, I found that as my boundaries are too close to the images' boundaries, the mods cannot recognize the lines. I plan to tilt the board and output images with larger area of dark. I will try again during the next week.
