BreatheEasy - PCB completion (Finally 😭 )

DEVLOG #4 Reworking the entire PCB

Hello Everyone!

As you may have noticed, a couple of hours ago I posted a devlog where I bragged about my first prototype (literally nothing to brag about).

Now, the PCB I had designed for after I make a complete prototype (once all of my parts arrive)

Turns out, that PCB was a complete non-working mess! 😐

So I spent an hour redesigning the whole thing and now it seems to be atleast half functional! Yippie!

The list of parts also changes a bit, because I decided using the analog output of the MQ-135 instead of the digital output because who doesn’t want more precise data which in turn resulted in me switching from a logic converter to a..

Voltage divider!

The rest of the parts stay the same.

Now the board is:

1. More organized
2. More compact
3. Even more cost effective (Resistor>Logic converter)

If you have any feedback or suggestions I’d love to hear them, and as always I wish you a good day!

(Btw I never mentioned this, but English isn’t my first language so…sorry for any grammatical mistakes )
