3Set ESP32 ESP-32S WiFi Development Board NodeMCU-32S Microcontroller Processor Integrated with ESP32 Development Board GPIO Breakout Board 30Pin

**** The customer experience with the ESP32 boards and their associated expansion boards has been a mixed bag, showcasing both functionality and significant issues that potential buyers should weigh carefully. Many users have reported that the boards operate well once properly configured, expressing satisfaction with their ease of use, especially in projects involving the Arduino IDE. The immediate compatibility with Windows operating systems and the straightforward installation process have been highlighted as major positives. Users have successfully utilized the boards in impressive applications, such as building autonomous systems and hydroponics setups, which further demonstrates the capability of the product in real-world projects. However, not all feedback has been positive. Some customers encountered serious issues with the power-up characteristics of the ESP32 boards, specifically that they do not automatically run their programmed code upon power-up; instead, the reset button must be manually pressed, which can be cumbersome. This particular problem seems to stem from grounding issues within the boards, leading to user frustration and concerns about safety. Moreover, there were comments on the lack of documentation, making it challenging for less experienced users to navigate the setup process smoothly. While the expansion boards garnered praise for their functionality, the faults with the ESP32-WROOM boards raised alarms about quality assurance and overall usability. In summary, while the ESP32 boards can enlighten various creative projects, potential buyers should exercise caution regarding quality and documentation Considerations. **
