SMD vs TFT: I'm asking you...

A project log for SoundWing Audio I/O Board

Sound in, sound out. Now both on one FeatherWing.

Here's a question for all of you folks following this project:

How much of an improvement would it be to convert all of the resistors to SMD (instead of TFT)? It would save a good bit of space, but I'm not sure what I'd be trading off for that.

(I'm re-learning electronics after some 40 years away, so bear with me here! I'm not sure there even were SMD components back then!)

For non-commercial projects where board space doesn't matter, then I suggest you use the components that fit your making skills. However, conquering SMD soldering opens up a whole new world of components and board real estate. Also, you'll be able to store and organize your unused component inventory in a much smaller space! It still blows me away to purchase that strip of 100 resistors for about a buck. My project probably only needed two.

Yeah... this one's calling for 9 resistors, so quite a bit would be opened up, and I might even be able to simplify the layout. Maybe I'll build it as an[other] alternate version, put it up as the main one for the contest, and decide later which way I want to go.

I do know that I have two complete projects in mind (different applications of the voice changer option) that would call for this board.

Thank you for the feedback!

You're welcome. I followed a similar path as yours starting about 6 years ago. Moving from Fritzing to KiCad also provided a fundamental shift in my designs. Good luck and have fun!
