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)

Vwry very good one,good price and good quality,wifi worked just fine i set it up with mucropython so easy but the pins was a little weak so be careful removing it from breadboard

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

Ok

Great for my daughters uni project

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 like it's supposed to. Had to play around with the boot button and resetting it in order to flash it. Eventually I figured it out and it's working well so far. A lot of micro usb cables only send power, so you probably need to buy one that specifically mentions it can send data and power. I'm giving it 3 stars because one of the pins wasn't soldered. It was of course a pin I needed too. I soldered it myself and it's all good now. But I didnt want to solder, which is why I bought one with header pins preinstalled lol.

Works great!

I didn't know i needed this in my life. this really help with capturing bt data and implmenting it into home assistant . i will be buying more.

Standard 30-pin ESP32S board. Of note: This uses the micro-USB plug, not the USB-C plug. Works. Flashes.
