  • There’s a protection diode for reverse current on the esp and your computers usb has quite a bit of protection against this kind of stuff.

    I wouldn’t worry about it. Even if there are errors in your cabling, it will very rarely break things if that is what you are asking. I catch myself all the time modifying things while it’s on which you aren’t really suppose to do.

    Faulty parts will happen but you will either be able to physically see the bad solder or you will have broken it yourself and will have seen the smoke coming out (mostly when using an external power sources). I also know you can break individual pins with negative voltage which is harder to notice. ESD can happen as well and will be much more subtle, but there should be some protection on the board for that.

    Its rare, but it’s always a good idea to have multiple esps, so you can so you can switch them out to verify it isn’t the chip.


  • Nothing makes genocide okay, full stop.

    We know Hamas sucks, the problem is that 70% of Israel’s victims are women and children, not hamas.

    The problem is that Israel funded Hamas and encourages them.

    The problem is that Israel is an apartheid state that fosters terror groups to keep control.

    But what really makes this a hypocritical farce is the fact that Israel not only tortures it’s prisoners as well, but rapes them too.




  • Few things to consider, you should have decoupling caps near the esp32s vcc and these need to be as close to it as possible. The antenna should be off the pcb completely and have gaps on its side, the module shouldn’t be in the middle of the board for instance.

    I think the new modules can be connected directly from usb and don’t need uart, something to look into.

    Tbh though, if it’s to learn, I would make an arduino first. The atmega chip comes in a dip format so you can make the whole thing on bread board first.

    A good ressource is the printedcircuitboards sub on reddit. They won’t have kicad projects but will have vaste amounts of schematics that you can study and copy with comments outlining mistakes and things of that nature.


  • If you mean with the little tin can, there isn’t much to add, so you can probably manage yourself by reading some guidelines, its essentially just adding a few capacitors, two buttons, a regulator and a usb2uart. You can find some pre-made examples if you Google “esp32 kicad github”.

    The stuff under the tin can is a bit more complicated.

    I’m not sure what your goal is though tbh. You need to understand the components you are using since there’s quite a bit of complicated rules and researching and drawing the schematic is a big part of understanding them.




  • I feel like they did the equivalent of watching it burn, as the fire department. Gaza was a fire they could have put out, they let it burn. They were making headway on climate change and then promoted fracking at the debate. Biden was clearly going to be a problem but they just let it burn until it was a mess.

    We have to be vocal. People want change. We can’t have another election where the dems run on “at least we aren’t pouring gasoline on it like the GOP”.

    They don’t need pity, their feelings don’t have to be protected. We can be harsh with them.






  • Are you happy? Is the vibe nice? Are people friendly? Are you being paid a fair amount or can you get more at an other job? Do they respect your private life, are they stressing you out? How is the commute?

    There are other things to consider then industry best practices. You might very well end up in a place that treats you like shit, is much farther and let’s you go the moment they don’t need you.
