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

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).

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'm quickly becoming an ELEGOO fan because of the quality of their product and the packaging and product support. After purchasing an Elegoo Arduino based robot we gain a keen interest in Arduino projects. This was purely influenced by our experience with Elegoo. When sourcing other parts from different vendors which in some cases were cheaper, none compared and often lead to returns for lack of functionality. Elegoo never disappoints and they are worth the price. Very responsive support, respond quickly, provide accurate information to ensure compatibility. I've also had issues with other vendors products the were smaller but usb ports failed and overall too much hassle to work with. Elegoo is different and though the size of these ESPs require 2 bread boards, that's a small price to pay for a quality product.

None of these ESP32s worked. They would connect and the IDE would say it uploaded, but they wouldn't reset and run the program. It wouldnt even run the blink example. Update: I eventually set the upload flash rate to 40mhz and they worked.

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

Great for home IOT projects. Code is available to work with Alexa.

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

No documentation comes with it such as a data sheet or positive ID of the board for which there are many variants. This makes it difficult to know how to setup an IDE or use the pinout.

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)

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.

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!

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!

All of them work perfectly, very good price.
