ESP32

I'm not worried, that the esp is actively powering the USB oort due to an external power source, because I don't use them. But is there a risk that the esp is sorting the power on the USB because of a mistake on my end by for example shorting 5v and Ground? Can it happen for any other reason? For example faulty parts on the esp?

It hasn't happened yet but I am worried that it might happen in the future.

I am not much of an EE and I was wondering if there is a place where I can find schematics of popular esp32 dev boards? My hope is that I can do placement and wire routing on a known good schematic. I know that PDF version of the schematic is available and technically it is possible to recreate it in KiCad but I'm hoping to find something in native KiCad format so that I have a good starting point for making custom board shapes.

It's a bit sad how deserted this community is, would love to connect more with other makers.

Let's rattle the cage a bit, who of you is here, and what are you working on?

I'll start: A wireless cryptographic keystore & signer. Keys are generated with the hardware RNG and stored AES-encrypted with the user's password, and you can request signatures via BLE.

Howdy, long time lurker!

I was wondering if anyone could give me a hand with trying to pull data from my Harmon Absolute43 pellet stove. Looking at the board, I see an RJ45 connector and thought "seems like a wireshark-like sniffer would do the job".

However, all searches end up looking at networking rather than simple data sniffing. Any ideas as to how to add a "bridge" that also stores the data? From there, I can do the publishing side of things, just the hardware component for me has me scratching my head.

I am looking for a MicroPython Caldav Package to connect my ESP32 to my Caldav server, e.g. Nextcloud. Did that anybody before?

I am looking for an #ESP32 Shield that adds #ZigBee communication to my ESP. Would be great if #MicroPython packages are available. Are there any known projects available, you could reference me?
