30PIN ESP32S ESP-WROOM-32 Board

This is a great value. Three ESP32S development boards with Bluetooth and Wifi for IoT projects. I wish it had USB-C, but considering this is a 3-pack of ESP32S dev boards with wireless connectivity and 16 GB flash for about $14, I'm not complaining. I've built a lot of projects using Arduino boards and Raspberry Pis but when I found ESP32 I never looked back. So many fun projects you can build with these really inexpensive dev boards that have wireless... so much less expensive than a Pi and so much more capable than an Arduino Nano. I really love making sensors, remote triggers, and other smart home devices with these. They seem to work well, and I'm really happy with them so far.

Do yourself a favor and order a name brand like Espressif. These are junk. The 5v bus provides about 1.5v. Happened with all 4 boards I bought. Bought Espressif boards after and they worked like a charm and provided 5v consistently.

Updated review -- the seller reached out to me to address this problem of receiving an incorrect and low quality/goopy ESP 8266, and replaced it with a correct, working ESP32. I was assured this was a one-time mistake that is unlikely to affect others, and they remedied the issue immediately. I am increasing my review to 5 stars for both the quality of the ESP32 boards and the quality of the seller support. Original, unedited review below: Well, it would be nice if you could count on getting all three ESP32 dev boards, but I only got two, plus an ESP 8266 covered in goop. One of the ESP32-WROOM-32D boards had a dent in the aluminum chip shield/cover, which shows poor product handling practices. Overall, they appear to be of low quality and careless manufacture, but my Arduino IDE did recognize all of them, so they at least work. I mean, this would be a good value for 3 of them, if you were sure you were actually going to get what you ordered. Since the boards work, I’ll say they’re worth 4 stars, but from this vendor, I’m only going to give 2 stars, since it’s not clear what you’ll actually receive, and how much goop might be on them.
