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

the reputation of the esp 32 is well known and these are an excellent example of the chip. I've made a number of successful projects with these boards and hope to make many more!

Both boards work perfectly right out of the box. USB-C connection is convenient, programming with Arduino IDE was smooth, and WiFi/Bluetooth performance is solid. Excellent value for the price.

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!

All of them work perfectly, very good price.
