First and foremost, the price is excellent. Getting three good quality ESP32 boards at this cost is a fantastic deal. They offer exceptional value for anyone looking to dive into smart lighting projects or other IoT applications.I’ve been using them for a few weeks now running WLED, and they’ve performed flawlessly. Setup was straightforward, and the pin layout is clear and easy to work with. I feel confident throwing these into projects without having to think twice.

These little boards are like having a Swiss Army knife for electronics projects. I started out thinking, "Let’s see if I can just blink an LED,” and now I’m building a DIY smart home like some kind of mad scientist. Setup is straightforward, and the possibilities are endless—Wi-Fi projects, Bluetooth gadgets, you name it. My only regret is not buying them sooner. Highly recommend if you enjoy feeling like a tech wizard tinkering in their lair.

This is truly my favorite microcontroller packaged into a great development board at an affordable cost.ESP32 works with Bluetooth Classic and BLE for short-distance data streaming. Two of these boards can be connected to each other and share data up to 80 meters away.The Wi-Fi connection is one of the most powerful features. You can connect the board to the internet and communicate with it via a web server. This allows you to make digital applications with physical and analog capabilities. The Wi-Fi communication can also be utilized to make a smart home. You can connect all the ESP32s together and control many different household operations via a Wi-Fi router.The cost is the third big pro. These boards are very affordable for what they can accomplish. This is a must for every circuit lab.I highly recommend this product to anyone who likes building things with microcontrollers.

Works fine on both Arduino and PlatformIO. You'll need to get the USB connection working and a serial modem to show up first, which needs a USB serial modem driver installed.On Arduino, use the board "ESP32 Dev Module", provided by "esp32". Set the upload baud rate to 115200.On PlatformIO, use the platform "espressif32" and the board "esp32dev". (Another review also mentions esp32doit-devkit-v1 works). You can use either the Arduino or esp-idf framework.I'm uploading a better pinout diagram I made.Actual review: Cheap, good price. Documentation for the devkit is not great. The amazon warantee is very unclear--says "contact the manufacturer or check their website", which doesn't exist. Luckily no problems yet.

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.

"If you're looking for a reliable board with plenty of community support, this is a solid choice. For simple and dependable projects, it works great. However, if you’re aiming for more advanced ESP32 features, you may want to consider a newer model. This board shines in straightforward applications where reliability is key.

All 3 of mine worked great, without defects. Has WiFi built in. I used one for WLED (Plug in and flash - super easy), controlling a servo via web server and (WIP) a midi controlled LED string. Works with Arduino software for programming

I bought the 5 pack of these, and initially the two that I've tried out of the pack I thought were working fine. Accepted programming and ran as expected. Until I went to move them to their actual intended work area in the other room, that's when it was discovered that they could not maintain a solid connection to my wifi. Bringing it back into my office, it jumped right on, so I open up the router and look at the connection status and see that the device is at a horrifying -75 dBm while just 4 feet away from the broadcast router. Moving out to the intended work area and if I angle it right, it would hit into the -80 dBm area if it had a connection at all, and then drop if it moved again or something else (like foot traffic) got in the way. Ultimately these will not work for my intended use. Maybe they work ok if you don't need to maintain WiFi with the device with distance, but if you do need that ability, this is not the board for you.
