Hosyond 2Pack ESP-WROOM-32 ESP32 Development Board WiFi + Bluetooth CP2102 Dual Core 2.4Ghz Internet of Things Microcontroller Compatible with Arduino

Used it for controlling leds with wled and it worked great! Cheap and reliable

Good product

These things are always good. Works like a dream!

I am using these to connect things to my smart home. They make good motion sensors connected to wifi as part of my home assistant setup.

These frankly are great setups, but if you don't know what you are doing, the esp32-cam is NOT for you. (You can learn, but it will be frustrating.)YOU WILL NEED A SERIAL CABLE THAT IS 3.3V DATA (Most are, but check, as 5V level will kill it) OR ONE OF THE PROGRAMMER BOARDS FOR IT.I had 1 of 2 fail, and it took a bit to get a replacement. However, That came and the seller was responsive. (Doing a bit of testing, it was the board that was bad, not the camera. So cool a spare camera (which pretty much only works with this.))They are good chips, if you program them with Tasmota, you can easily adjust the setup for them. They can be setup pretty easy, but the first flash can be a problem the first time you do it, and I did have Tasmota corrupt it's settings, not want to work with the easy gui tools and had to go back and use the esptool.py to flash it clean. (As far as I tell that's Tasmota's issue. Worked fine flashing with the esp32-cam example program in Arduino, then back, if you do use the esptool.py to flash the *factory* bin to clear the settings, the normal precompiled ones leave the settings intact.)Pros:CheapResponsive SellerCheap wireless camera that only requires a 5V power source!Extra pins for SD and/or other sensors (presence, temperature, etc. Just about anything that Arduino supports works.)Cons:1 failed, was replacedInitial setupEven with the failure, There's not much that's in the same price range. It's pretty good, though you trade framerate for quality or vice-versa. (only a few fps at 1600x1200, or 1280x720 (720p) to 60 at lower resolutions) So I'll give it 4 stars.
