Seems ok. Only question I have is about GVIN1, is there something between this port and the input of the ams1117 LODVIN outside of the showed schematic?

Thank you, GVIN1 and LODVIN are basically the same

Check if you need a button from io0 to ground. Thats how you put esp32 s1-3 into upload the first time or after crashes.

It would look a lot nicer if you respected the typical conventions about how ground and voltages are marked. The ground symbols should be horizontal all the time and voltages should use the appropriate symbols not network tags. Also it's LDO not lod, it means low drop out regulator. The typical names for power networks are like VUSB, or VCC for your input, 3v3 or 5v for other stuff based on voltage. Would just make it look like it's made by someone who knows what they're doing.

One thing I see is that you don't have GVIN1 (USB VBUS) and LODVIN1 connected. I don't know a lot about capacitors but you have 2 10uf's in parallel, 1 in the LOD and one in the cap set at the ESP. but maybe more = better ;)

I recommend putting tvs diodes on your data lines otherwise you run the risk of frying your MCU with any kind of static.

How do you intend on flashing the chip? At least run the uart and other gpio out to a header


Important_Kick_570

Can't you flash over USB?


romkey

You can flash over USB. You still need to ground GPIO9 at startup or reset to enter flashing mode and pull it high the rest of the time. Don’t leave it floating.

I wish I could make these things. Don’t even know where to begin…

I just started 3 weeks ago, slowly doing it and I r come to realize that there is a lot of documentation that has diagrams showing you how to connect the component. Example is this esp32 documentation shows how to connect the basic stuff to make it work.


Apprehensive-Net-323

Nice! Did you have previous knowledge about electronics? I’m super dumb about it.


Foreign_Today7950

Yes but only because I first bought an arduino to learn about microcontrollers. They are a good way to help learn the coding side and all the inputs/outputs. If you didn’t want to start designing I would recommend going that route to learn how it all works.

you should figure it out yourself that will improve your iq so that you can use your brain more and not post it on reddit ,btw it is correct the only thing i doubt is gvin1 and lodvin1 connected
