ELEGOO 3pcs ESP-32 Development Board, USB Mirco, 2.4GHz Dual Mode WiFi+4.2G Bluetooth Dual Core Microcontroller for Arduino IDE, Support AP/STA/AP+STA, CP2102 Serial Chip

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!

Nice upgrade from Arduino Uno R3. Good price too. Make sure you use a true USB-C data cable and not just a charge cable as they look the same and power LED will light, but no communications with charge cable as there are no data lines in it. After I figured that out the unit shows up in Device manager correctly, even on an older Windows 10 PC from 2010. Very happy with these units.

Purchased a 2-pack for $20.99 in September 2025. I needed a microcontroller for a WLED project and decided to go with Elegoo since I’ve had good luck with their products in the past.

As expected, these worked flawlessly. The build quality feels solid, and setup was painless. I especially appreciate that Elegoo has switched to USB-C—no more digging through drawers for a micro USB cable.

The Wi-Fi range is excellent using a 2.4 GHz network, and the boards integrated smoothly into my project. I’ve now got my LED lights running perfectly and couldn’t be happier with the result.

If you’re looking for a dependable and affordable ESP32 board, these are a great choice. I’d definitely buy them again for future projects.

Rating: 5/5 stars.

TL;DR:

Reliable, affordable ESP32 boards with USB-C and great range. Perfect for WLED or IoT projects. No complaints—5/5 stars.

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).

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.

His takes IOT making to the next level. I can still program these using the ArduinoIDE but no longer have to have the finished model connected to a PC. With WiFi and Blue tooth connectivity, the ability for me to make untethered models has improved so much.
So far I’ve not had a single failure with any of these, and with an OTA firmware capability I can update all my. Uilt models remotely.
They are less than 2 ounces so pise no issue for flying models, and run on either 3.3 or 5v so choices of battery is available.
Being a WROOM board all the antenna are built in, and certifications for wireless are incorporated.
At C$10 each, these are a great deal.

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!
