About this item
- 1. The complete solution takes up the least printed circuit board area. This board is used with 2.4GHz dual-mode WiFi and wireless chips using 40nm TSMC low-power technology.
- 2. The best power and RF characteristics are safe, reliable and scalable for various applications.
- 3. Meticulous workmanship: The meticulous design, perfect in workmanship, durable and long service life.
- 4. Compact and portable: being so mini and light-weight, this product does not take much space and can be easily taken away.
- 5.For Arduino IDE,choose ESP32 DEV,make sure that your program or run a program smaller than the ESP32 configuration
- 6.The maximum operating voltage of the ESP32 is 3.3V. The ESP32 has an on-board voltage regulator that can withstand voltages up to 5V using the VIN and GND pins. Once a voltage is input to the ESP32 development board's VIN pin, that voltage is passed through the ESP32's on-board voltage regulator (AMS1117), which outputs a constant 3.3V, which is the board's operating voltage. Note: The maximum operating voltage of the ESP32 is 3.3V. The maximum voltage that can be applied to the ESP32 Development Board from the VIN pin is 5V.USB power supply is 5V.
- 7.you need to driver the CP2102 before you can start using it
- 8. Durable material: This product is made of high-quality material, durable, long service time, firm and stable in use.

- Reviewed in the United States on March 5, 2025Size: ESP32 30PVerified PurchaseNo issues, great price and was able to code them and install them with ease
- Reviewed in the United States on March 8, 2025Size: ESP32 30PVerified PurchaseWorks awesome but on one of the three boards I got the micro USB port is kind of defective. The USB plug doesn't stay plugged in very tight. It makes enough contact though to connect to the board.
- Reviewed in the United States on May 15, 2023Size: ESP32 30PVerified PurchaseThis works great if you are wanting to get into C# and nanoframework on embedded processors. these have the blue led on the board on gpio2. There is almost NO documentation for this online as it's a knockoff of a knockoff of a knockoff. there is only a single jpg of the board pinout floating up in the questions that is a link to a google drive location. For a cheap start these work. Be aware that they dont have the full amount of memory so you are not going to do everything you can on a real esp32-WROVER or real ESP32-WROOM. They are trying to claim they are genuine but the laser etching on the tops is nothing like the real ones I have. And the real ones are 3X the price so I knew I was getting something cheaper.
These are great to tinker with and for projects. and awesome to give to friends wanting to get started down the path of programming ESP32 with C# and NanoFramework.
- Reviewed in the United States on January 28, 2025Size: ESP32 30PVerified PurchaseI don't plan on using these anytime soon but they look great. Air sealed packaging with a little foam stuck to the pins so they didn't pierce the packaging or get bent. It arrived so fast I was not expecting that kind of fulfillment AT ALL. 10/10 I saved the link in case i need anymore in the future
- Reviewed in the United States on February 1, 2025Size: ESP32 30PVerified PurchaseAwesome boards, fun experiments, and untold amounts of data. These things are beast.
- Reviewed in the United States on January 14, 2025Size: ESP32 38PVerified PurchaseUsed it for my own project for college and was able to get an interviews from my project!
- Reviewed in the United States on September 22, 2024Size: ESP32 38PVerified PurchaseGreat value IoT board, tested with Arduino 1.8.19 on Debian 12.
There is no Teyleten Robot in the library so I used "ESP32 Dev Module" from Espressif's ESP32 Arduino core.
The pinout is the same as Espressif's ESP32-DEVKITC board.
The SD0 pin is mislabeled SDD.
There's a bug in the build where you have to
rm /tmp/arduino_build_*/includes.cache
after every compile.
