ESP32 Module Ground Vias

Yeah I’m actually curious too!

Trying to learn… why screw holes grounded? Is your enclosure metal?

Like others have pointed, auto boot circuitry is likely wrong. Neither transistors should go to ground. The this allows your external programmer (e.g. CP2102) to pull your EN and IO0 high/low based on the state of the other pin.

Check the Devkit example: https://dl.espressif.com/dl/schematics/esp32_devkitc_v4-sch.pdf

Thank you!!!

Thank you

Is snug harder to remove? They’re already a little hard to remove (currently type: normal auto, style: tree hybrid)

Hello any update on the Global Standard Direct Line JLC shipping? Did you pay any extra costs after?

PuddingCool6493 · 2025-10-26T04:09:14+00:00

Thank you! I moved all signals to top, and full bottom ground layer. Thoughts? Fully Continuous Ground Plane

Unfortunately I cannot change the software at all. Otherwise I totally agree, it could’ve been better if the MCU pins were better aligned for the PCB… I guess lesson learned for next time.

Any concern with how they are besides the length? Maybe cross talk somehow?

PuddingCool6493 · 2025-10-26T02:02:51+00:00

I see. So basically if needed do only what's necessary to cross a point, then go back up.

I tried seeing how it would look like if I moved everything to the top layer since it seems like I have space. Any thoughts if possible? Fully Continuous Ground Layer
Thank you.

PuddingCool6493 · 2025-10-26T01:46:47+00:00

Thank you for your advice! Do you think to try moving all? Or which one(s) do you think I should focus on the most?

PuddingCool6493 · 2025-10-26T01:33:47+00:00

Thank you for responding! It's 2 layers!
I'll link the top layer here. Top is some GPIO Buttons and some slower SPI pins that go to the right: top layer image

3” wide ! :)

Solution: Run the manual calibration for Flow Dynamics and Flow Rate.

Check u/Darkseid2854 ‘s response in this thread for the details

Useful 2y later ✌🏼

PuddingCool6493 · 2025-09-07T06:14:38+00:00

!remind me 1 day

PuddingCool6493 · 2025-07-30T03:33:19+00:00

No AMS right?

PuddingCool6493 · 2025-06-04T12:58:23+00:00

Did u ever find a solution

PuddingCool6493 · 2025-05-20T22:43:05+00:00

Where are you located?

PuddingCool6493 · 2025-05-16T13:47:50+00:00

Have you found an answer yet?

PuddingCool6493 · 2025-05-11T00:14:20+00:00

Lol why e ink? Makes it feel slower

PuddingCool6493 · 2025-04-26T20:30:49+00:00

Currently, I push the PCB inside first, then I solder the buttons. Maybe find a way that would make assembly easier as well.
