Review: No Problems-And They Fit on a Standard Breadboard - There are a number of ESP-32 dev boards, and I was completely new to these (last board I used was an Arduino AT-Mega 2650). I had tried to use an ESP8266 for my current project, but discovered there were not enough usable GPIO pins on the 8266 boards. I chose these HiLetgo boards for three reasons: (1) I had good experience with several HiLetgo modules in the past, (2) These are smaller than many of the other boards; as a result they can be used on a single breadboard and still expose a socket on each side, and (3) They have more Gnd and Vcc pins than some of the other boards. Upon receiving the boards (in 24 hours with Prime), I used instructions published by Random Nerd Tutorials (an excellent source of detailed information) to install these on my MacOS/Arduino 1.8.8 IDE. I had both modules up and running the demo software within 10 minutes, without any problem. They upload at full speed (921,600 Baud); I am told that many of the other boards will only do 115,200. The only slight inconvenience is that there are no pin labels on the top of the board (there was no room to print them, since the board is smaller than many of the others). They are labeled on the bottom, however, and accompanied by a large diagram of the pin-out from the top view. These have plenty of GPIO pins, and I am very satisfied with them so far. No struggles, mysteries, or obscure instructions, and no peculiarities or non-standard features. This appears to be a solid platform for our development.
Review: Great product, works great - I've purchased one of the HiLetgo ESP-WROOM-32 ESP32 ESP-32S Development Boards. The board works great and it looks well built. I liked the readable schematics too. However, when I use an external 3.3V power supply to power the board, my code won't run. The 5V red led turns on and the IO2 blue led keeps blinking. When I disconnect the external power supply and use the USB cable, everything works fine. If you don't plan on using an external power, it seems to work fine. In my case, I may have to look for another manufacturer. I've submit a support request w/ HiLetgo and will update this review if there's a solution to this issue. Updated on 6/11/23 It turned out there was a cold solder joint on my own board (not HiLetgo's) that was causing the issue. I was able to identify the problem on my own but HiLetgo did respond to my inquiries. I'm changing the rating to 5 stars and will be buying more boards!

## Questions & Answers

**Q: is there a pin out diagram for this board ?**
A: On the board I received today, October 18, 2017, there are NO pin labels on the bottom of the board.  In fact, there is no labeling at all, contrary to the product pictures above.  The board has no pin labels on top, either.  The NodeMCU documentation I have just found has a completely different set of pin assignments as compared to the pictured pin labels above.

**Q: I've downloaded every driver i can find and neither my pc nor my mac will recognize this thing. help?**
A: One of the reviewers said it required CH210 instead of the usual CH340 or CP2102. Since this is an old question it may not help you, but I hope this helps someone down the road,

**Q: Are these Rev0 or Rev1 of the esp32 chip?**
A: The chip revision is 1. I obtained this by running the code to retrieve it from the ESP32 module itself, so I know it's accurate. My delivery date was Jul 12, 2017.

**Q: set esp32 as web server, but lost connection after 1 minutes, maybe wifi sleep, is there any way not wifi sleep?**
A: This ESP32 has dormant function, but only if you write a command in the software and enable it, the dormant function will be eabled. If like this, please remove this command. If you didn't write such a command, the disconnection may be due to weak wifi signal or the wifi has large interference.

### ⭐⭐⭐⭐ Solid ESP32 Board – Great for Haptics Projects!
*by A***G on September 8, 2025*

I purchased this HiLetgo ESP-WROOM-32 ESP32 Development Board for a custom haptics project, and overall, it performed really well. Setup with the Arduino IDE was smooth, and the onboard WiFi + Bluetooth functionality made it easy to handle both data transmission and peripheral control. The dual-core processor gave me the performance I needed for real-time feedback and signal processing. The board was reliable throughout development—no flaky connections, and it powered all my components without any issues. It's compact and affordable, making it a solid choice for prototyping. The only limitation I encountered was running out of storage space for my code. That’s more of a code management issue on my end, and I may need to refactor to optimize memory usage. Just a heads-up if your project has a large codebase or uses a lot of libraries. All in all, this board met my expectations and worked well for my needs. Would definitely consider using it again for similar projects! ⚠️ Disclaimer: This review is based on my personal experience and is provided for informational purposes only.
