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 Compatible with Arduino IDE (1 PCS)

All three boards work just fine. No damages to any pins. This will not work on a breadboard. You will have to use jumper cables like these https://a.co/d/00ZlD2vZ. There is no documentation. Use the pinout diagram provided by the seller. WiFi also works just fine. Wrote a test esp-idf program to do a quick test. All three boards passed with zero issues. See video.

Ordered these for a 3D project. Love them and has ordered more tan once.

I was investigating how to enable bluetooth with my Homeassistant installation and found documentation on creating a bluetooth proxy. This item was linked directly on the ESPHome website, which also includes a web-based firmware flasher. Encouraged by how easy this could be, I made the purchase. The competing option was a M5Stack Atom Lite, which looked quite promising as it comes within a case already. After weighing the shipping times, I went with this product. The two are essentially the same price if you factor in a separate case for the ESP-WROOM-32. Sifting through the reviews here, I found that manually installing drivers for the board would be required. If you just plug in the device, Win10 shows a popup but it does not actually install the needed drivers. You will need the easy to google CP210x USB to UART Bridge VCP Drivers, CP210x_Universal_Windows_Driver.zip available from Silicon Labs. After that, the web app flasher was easy to run. It wrote the FW needed and then lets you specify your wifi network. I had read many reviews that were disappointed with horrible wifi range. I am 1 floor below my router and it shows -71dB signal. Not great, but still functional. Maybe that's not bad considering there's no antennae. Other wifi devices in the same room were about -65-70dB. Immediately after connecting to wifi, Homeassistant recognized the device and it was easy to add it as an ESPHome device. It easily found the 3 bluetooth thermometers I wanted to connect (Thermopro TP357). I haven't had any notable dropouts for this first week but will continue to monitor. As the last step I am purchasing a case for the board. There are some generic plastic boxes available on Amazon, but I decided to go with Etsy for a custom 3D printed one.

Works great - no surprises . You have to dig a bit to find info on the ESP32 connect , but worth it !

I love the product i just wish they would've provided the dimensions of the holes. They only show the dimensions of the outer part of the chip but nothing for the holes which makes it harder to create a housing for it. Otherwise, I love the product.

I used these for ESPHOME bluetooth proxy to extend a weak bluetooth signal. At first I thought there was an issue with these boards because they would lose signal every so often. After further testing I realized that the micro usb cable powering the chip would lose voltage when the wifi would increase power. I switched from a cable that was a foot to a cable that was 6 inches and all the problems disappeared. I hope this helps other people with similar issues.

These will not connect to the pc. I've tried it as ESP32, I've tried ESP-WROOM, I've tried an exhaustive list of different esp32 boards in Arduino IDE, these will just NOT connect at all. The pc doesn't even recognize them to upload code to. Waste of money

I picked these up to make a cheap COB LED strip smart. It only came with an RF remote which is not sustainable. They arrived without documentation, but that isn't a problem for me. My will is stronger than that. They arrived sealed in antistatic bags and looked new. The onboard USB port is a micro USB. I used it to flash WLED and setup wifi. I powered the board and the LED strip from the same power source because they used the same voltage. Then, I used a GPIO pin to communicate with the light strip. It was easier than I thought it was going to be. A heat sink is not recommend because the ESP chip does not produce much heat. They do not include a display. The quality is fine for my purposes. If you are just getting started with something like this, read the WLED site or ESPHome. Step 1. The website will flash the firmware for you.

Really useful microcontroller

I had a few old Chinese addresses able rgb strips that just had a very basically controller and crappy power supplies. Install WLED on this board and now all the strips are smart light strips and they perform better than some of the other branded RGB led strips.

Am able to connect sensors and host a server on it!

Ok
