ELEGOO 3PCS ESP-32 Development Board USB-C, 2.4GHz Dual Mode WiFi+Bluetooth 4.2 Dual Core Microcontroller Support AP/STA/AP+STA, CP2102 Chip

These worked great for my IoT projects. Easy connectivity and the usb-c port was easy to use. Worked great with the Arduino IDE

I've purchased two sets of these now, as well as other brands that quite frankly I found disappointing for various reasons. All of the boards have worked flawlessly, some despite literally dozens of code downloads while debugging and expanding designs. The biggest advantage of these boards over some of the other variants I've purchased is that I've never had to hold the boot button when downloading code from an Arduino IDE. This has not been the case for some other manufacturers' versions, and given that some of my larger programs can take several minutes to compile before downloading, it's quite inconvenient having to pay attention to be able to press and hold the boot button at the proper time. (That said, there is the trick where you can jumper data pin 0 to ground until after downloading is complete, but depending on whether you are prototyping or have it installed in a way that the pins are no longer easily accessible, this is not always a convenient solution.) So while these do cost a bit more than some alternatives, the fact that they reliably program without having to hold the boot button is, at least to me, worth the small increase in cost. And Elegoo has great documentation (which is more relevant to some of their other products, but I mention because it just goes to the time and quality they put into their products).

Very nice, if a bit older, MCU. Connects well, has the right size, works well and its good value for the money.

It took a little bit get get started with this dev board, but I am mostly very pleased with it. I am using it as a replacement for an Arduino Nano ESP32. I do not know how it stands up to other ESP32 boards. Size: Comparatively, it is physically larger. It may not fit into the project I was hoping it would, but that's on me. The real issue with the size is that it does not fit on a standard solderless breadboard. It is too wide, and you can only use one column of pins on only one side. It is possible to remove the power rail from the edge of one breadboard and join two of them together for a bit more space, but that feels like a hack fix. Usability: I initially had trouble getting Arduino IDE to recognize my board. I could see my PC (Windows 10) was working on installing something the first time I plugged it in and got confirmation afterwards that the device was ready to use, but it still was not connecting in Arduino IDE. The fix was to install a CP210x driver, which instantly solved the problem. Compatibility: As stated, it works fine in Arduino IDE. You just need to download the esp32 board manager from espressif. I am using the ESP32-WROOM-DA Module board (I hope it is the right board, but it *does* work). Once I got it running, it was as easy as reassigning the pins to match the new board's output. It runs the code perfectly. I may even slightly increase the maximum speed of my LED matrix animations, but I'm not totally sure on that. Value: You get three boards for less than the cost of a single Arduino Nano ESP32. As far as I can tell, they are more or less equivalent in functionality and specs, making this set of three boards a great deal. Overall I like it quite a bit. I wish it were made more clear that this was specifically an ESP32 WROOM 32 board, meaning it has two cores, as opposed to a standard single core ESP32 board. Ultimately, it does not seem to make a difference in my use cases, and may possibly even be better. Both run at the same 240 MHz. The box it came in even says "ESP-WROOM-32" where the product image says "ESP-32", so I initially thought I got the wrong item. That, and the issues with the breadboard are why I give it 4 instead of 5 stars. Still, I am very much enjoying them so far and will purchasing more of these as needed.

Great product

Works as advertised no Problems yet. Look and feels appropriate. Reasonable

Not all ESP32s are the same! Nowhere in the description or photos does this show an ESP32-WROOM-CE board, but as it turns out, what I received are a set of CE boards, which are cheaper, glitchier, and not as stable as an ESP32-WROOM. I discovered this when none of this 3pack of board would flash WLED by any means (web installer, PlatformIO, etc). If you order these, you will not likely get the board you think you're going to get. Hoping to still use these for basic builds, but definitely do not use these for anything you need to depend on. This is why I get the electronics I actually need to work reliably from DigiKey, Adafruit, or literally any legitimate retailer now.

These little things are awesome! You can do just about anything with them!

Great quality, worked straight out of the box, was flashing with platform io - glad they supported 8 RMT FastLed lines, was disappointed by the S2 Mini’s previously, these worked perfectly, first time (though i did kill one by accidentally tying IO lines together)

NOTE: EDITED!! Original review text left intact below, but read to the end for update/ additional details. This product arrived very nicely packaged/protected for shipping, but otherwise (in my humble experience) not a good choice for your first steps into the realm of ESP32. There was absolutely no documentation included (except for the pinout image that you can find in the product description here on Amazon.) My bad I guess for not checking into support prior to purchase. About a year ago I had purchased an Arduino "Mega" starter kit from Elegoo, as my first experience with microcontrollers. I was quite satisfied with the support/documentation included with that kit, and since that initial kit purchase I have gone on to successfully complete a number of projects utilizing various flavours of Arduino boards, interfacing with a variety of integrated circuits, sensors, screens, etc. So while I'm new to ESP32 I'm not a totally clueless noob when it comes to programming microcontrollers. Unfortunately that previous Elegoo Arduino kit experience was a major factor in my choosing these particular ESP32 boards. When they arrived I was dismayed to find no documentation, no support of any kind, not even a whiff of the existence of this product on Elegoo's website. I have installed ESP32 support in my Arduino IDE and it seems like the IDE is able to connect to the board. I have one of the boards mounted in a breadboard right now and powered up via USB - but have yet to get any kind of meaningful response from any of the test sketches I've uploaded so far, such as a basic LED blink. And before you ask, yes the LED works fine and I can light it up directly from the 5.0v and 3.3v pins on the ESP32 board. EDIT: Update!! – A representative from Elegoo reached out to me within hours after I had posted this review, offering assistance. They provided some additional resources that got me going immediately. I am very impressed with their speedy support – but only wish they could have simply provided a link to those resources right up front. (like a slip of paper (in the package along with the boards) that included the link to the resources ?!? I have upgraded my rating from 3 to 5 based on their super quick support response, and since all three of the boards are now tested and working flawlessly. Highly recommended with the caveat that if you're new to ESP32 (as I was) don't hesitate to visit the support page on Elegoo's website and request assistance / resources. Based on my experience they should get back to you promptly!

Arrived well secured and protected from damage. Items as advertised, 3 x ESP32 boards with header pins attached, all supporting USB-C. Initial testing shows they are operating as expected when loaded with firmware via Ardunio IDE. Good price, good quality, will buy again!

I’ve been using this ESP32 for some prototyping, and it’s been excellent so far. It works reliably, has all the features I need, and the performance is solid. For the price, it’s honestly a great deal. Perfect choice for hobby projects or quick experiments.

awesome piece of kit. worked straight away and was easy to setup under ESPHome and Home Assistant
