Works, reliable, flashes with no button pressing (on linux)
I got these to replace some nearly identical ones from a different seller which had super flaky wifi (it turned out due to counterfeit USB chip leaking high voltage to the ESP32). I'm happy to report that, despite having a no-name USB chip (CP2102 clone, I think) all the voltages measure as they should (unlike the other brand) and the units work so far flawlessly. I bought these from KeeYees this time because I had purchased some ESP8266s from them a long time ago which have worked great for years, and so far it looks like their ESP32s are similarly well-enough made. So, if you are scratching your head over which brand of this board to buy when there seem to be so many that are exactly the same: Beware they may be the same design but the components matter, and so far for me at least KeeYees has sent me good, working boards, spanning multiple years, which I can't say for some other random brands/sellers.

Great with WLED
I used one of these programmed with WLED software to run 12V LEDs on my Christmas tree. It was a big project since you need a 12V power supply, a voltage converter (to get the 5v this device needs) and a box to connect multiple strings of lights into a central hub. Worth it. In the video, you might notice the star is doing its own thing. It's got another one of these microcontrollers wired up to a dozen white LEDs with some custom code (not WLED). That one runs off a USB plug which is a lot simpler.

Work well do the job
They work for projects and such. Standard esp32

Needed this device together with a breakout board with screw terminals for easy configuration
I'm using this as a testing unit for a product I'm making.

These are cool
I haven’t used these particular ones yet but I have another that works great. The reason I bought 2 more here.

I can't use it with the Arduino IDE and I don't know who to ask for help
ANY SUGGESTION to be able to connect Keeyes ESP32 to ARDUINO IDE by USB Port, which fails me? .I bought 2 of these ESP32 from KeeYees. Now I'm trying to use it with Arduino IDE but it doesn't connect with the Port. I have another ESP32 chip from another brand and it does connect and I was able to test it by loading a flashing LED Skecht. Will it be necessary, as the Keeyees manual says, to install "CP2102 driver"? I tried 2 different cables, both worked fine with the Other motherboard from a brand other than Keeyees. And also tried to go to their site. It seems that I don't know how to buy online since I don't know when a supplier is reliable or if the product is good or not.

No wiring diagram means it won't work
WHy isn't there a diagram for the wiring included? I've tried D2,D4 and the RX pin for data and WLED still won't work!
