5PCS 38pin ESP-WROOM-32 ESP32 ESP-32S Development Board 2.4GHz Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller Processor Integrated with Antenna RF AMP Filter AP STA for Arduino IDE

ESP32 worked as intended, but configuration needs to be performed in the Arduino IDE and on a Windows computer before it can be used. Make sure you use a USB cable that is NOT a "Charging Only" cable! Some USB cables only have power wires and no data wires in them and will only recharge USB devices, you will need a proper USB Data cable to be able to install and program an ESP32 board.How to Set Up Arduino IDE and Windows:--- In Windows, install "Silicon Labs CP210x USB to UART Bridge" driver first. Use Google to find "cp2102 usb to uart bridge controller" and download drivers from silabs website. This will give the ESP32 board a COM port.--- In the Arduino IDE, click on 'Tools' -> 'Boards' -> 'Boards Manager...' and scroll through the list until you find "esp32 by Expressif", and install it. This will install ESP32 board support into the Arduino IDE. Be careful Not to install 'Arduino ESP32 Boards' support because it will Not Work with these boards.--- In the Arduino IDE again, make sure you have the ESP32 board plugged into a USB cable that supports data throughput (not a Charging Only cable), then click on 'Tools' -> 'Boards' -> 'esp32' -> 'ESP32 Dev Module', and then set the COM port for this board (mine was COM3). This will be the board that you want to program.--- Start programming and have fun!Follow those steps and you'll be programming in about 15 minutes. Enjoy!

I'm working on a shock and tilt-driven display that takes input from a 9 axis accelerometer and writes to an 8 X 32 WS2812B LED matrix. The micro controller meets all expectations.Note that GPIO pins 8 - 13, the Flash pins, are unusable, so you might as well buy the smaller version. But it's no big deal. Also, the pinout is out of order, again no big deal. I don't know if any breakout boards have the pins in numeric order.I would buy them again.

1 out of 5 was able to connect to a network. Used a ton of these in the past. Never had an issue. These are junk. Don’t purchase if using networking or for WLED. Works fine in AP mode but refuses to connect to any networks

Great value and reliable. It’s amazing what these ESP-32S boards have for capability and the available software out there to program them. Unlike some ESP32s, their 38 pin configuration lines up with standard project boards. There are also many affordable relays and sensors out there to integrate them with. Recommended.

It's super convenient to be able to pick up a 5-pack of ESP32's for a project with a quick turn-around time. I needed to prototype the interactions for an art installation with 4 weeks of lead time. All 5 of my boards powered on and programmed right away (had to hold down one of the buttons to properly program, the button that's NOT EN). However, over the next few weeks as I shifted to making something that would be reliable for several months, the lower quality of the boards started coming through. Some of the boards had the headers soldered at a slight angle, which made them impossible to breadboard without forcibly bending the pins. Two of the boards had failed by the time I needed to finish the installation, and I didn't do anything to let out any magic smoke as I was using them. Luckily, I only needed three for the final version, but I'm not totally sure those will stay alive for the duration of the exhibit, so I'll go for higher-priced, but hopefully higher-quality ESP's for replacements.

These modules work as good as any other ESP32 controllers. Mine came with bent pins though, likely damaged in shipping; so I had to bent them back; otherwise they seem to be fully functional

I really like the USB C and the build quality seemed good. However the WiFi is somewhat broken. I verified across several boards that is can connect to my google nest wifi but not a DDWRT buffalo router or a brand new travel router I bought for a project. Other ESP32 and other 8266 can connect just fine to all 3 WiFi but for some reason these chips refuse to fully connect. I was monitoring the DDWRT wireless clients page and would see it briefly connect then disconnect. I tried different power sources as well PC USB and 2.1A cell phone charger. If it connects to your WiFi they are great boards, but this is a deal breaker for me.

Very good ESP32 modules. They been working fine for me.
