8. Electronics design¶

This week I worked on defining my final project idea and started to getting used to the documentation process.

Assignments in this week¶

Group Assignment:

[x]use the test equipment in your lab to observe the operation of a microcontroller circuit board
[ ] send a PCB out to a board house

Individual assignment:

[ ] use an EDA tool to design a development board to interact and communicate with an embedded microcontroller,produce it, and test it
[x] extra credit: try another design workflow
[x] extra credit: design a case for it
[x] extra credit: simulate its operation

Learn test equipments in my lab and test the boards¶

As a former embedded engineer, I can basically use test instruments. At present, I have found test tools such as regulated power supplies, voltmeters, and oscilloscopes in Chaihuo Makerspace. In addition, I have also used handheld oscilloscope products such as ADALM2000 to perform some basic circuit measurements.

Learn about KCad.¶

As a former embedded engineer, I have used Altium Designer 10 for circuit drawing and PCB drawing, but these experiences were at least 8 years ago. I still feel very excited when I start using drawing tools again. This time I chose KiCad as a learning tool and started this week’s assginment.
