AITRIP 3PCS Type c 30pins CP2102 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

Let me tell you about this **AItrip 1PCS Type, C ESP32 ESP, WROOM, 32 Development Board, it's honestly amazing. I’ve become quite the tech enthusiast lately, and this little device has seriously made my projects so much easier and more enjoyable. What I love the most is the WiFi and Bluetooth capability, which means I can set up various projects without any hassle. The dual, core microcontroller really enhances the performance, making it perfect for everything from simple tasks to more complex applications. The best part is that it’s durable enough to handle the usual wear and tear in our busy household, which is always a plus for me. At the end of the day, I'm really happy with this **AItrip 1PCS Type, C ESP32 ESP, WROOM, 32 Development Board.

Great ESP32 device and though there's no documentation. Anyone who know what these are don't need any instructions. Was able to flash a custom firmware to use on a small build and everything works. All 3 module accepted the flash with no issues and was very easy to use and flash. So far it's working and I'm able to stream my audio from the phone to another Bluetooth device. Great little module for the money and there are endless features you can do with these ESP32 modules.

I bought this ESP32 for a digital seismograph I'm working on. The functionality of this thing is amazing. I was able to hook it up to my ADC without any problems, alongside a micro SD card reader. Not only that but I was able to run a local webserver in which I could see my graph. It's pretty fast too, I haven't had any delays with processing data at all. It's small size and very little required power source makes this great too. It's versatility will allow you to pretty much use any type of electrical component with it, and I have not runed into any compatibility issues so far with any of my parts. Only thing I would consider a con would be that you'll have to learn C++ in order to program it. Overall, I would recommend this board for any type of low power project you may need.

Leaving a review so that others don't struggle the way I, as a newb, just did, jumping into electronic engineering as a hobbyist. The specific boards I received were the ESP32-D0WD-V3 (revision v3.1). You can find the datasheet for them in the Espressif Systems documentation. I bought this to play around with Home Assist and Meshtastic... And it's been an experience to say the least. None of the markings of the physical board lead me to the correct documentation, so I advise anyone buying ESPs off amazon as a newbie, to use the "esptool chip-id" in your command line or terminal to figure out exactly what board you are working with. Now you may need to do a bit of internet searching to figure out how to do that, but if you are buying development boards it's a necessary evil. The boards work as intended but I'm giving 4 stars because it's unclear what exact boards you will receive, and knowing that is half the battle. For anyone getting into Meshtastic, I'd say for ease of use, don't get this particular board as it is not supported natively, I had to build from the source code to flash this, which was impossible until I found the correct documentation. (As of Oct. 2, 2025, I'm still working on cleaning up the code and before I do a pull request to hopefully add it to their supported hardware.)

I bought a set to use as a Bluetooth proxy with Home Assistant and things that were unstable and laggy are now basically instant and perfect. Love it and now I'm trying to figure out how to use the others. Also, these are quite small and super easy to power. Basically, super great value. Oh, if you have issues use ESPHome to flash projects onto your ESP32? Make sure to download the drivers. That threw me for a loop for a bit.

Works great!

2 out of 3 worked. The bad one couldn't connect. Too bad. Other 2 work as advertised to drive my led projects.

These were too wide for the breadboards I had on-hand. Only one row of pins were available depending on which side you chose.
