ESP32 Development Board Integrated 0.96 Inch OLED Display,CH340 Driver,WiFi+BLE Wireless Module,and Micro USB Works Great for Arduino/Micropython(Pin Header Soldered)

After seeing several negative reviews, I almost did not buy it, but then decided I would try it. I followed a YouTube tutorial. Using the built-in examples, they worked. I was able to modify the built-in example and get them to work. I have some experience with Arduino. I like this device and will consider it for future projects.

The integrated OLED and overall MCU flexibility have made this model my go-to ESP32 device! I've loaded multiple diverse firmwares onto it, and run many many sensors with it under the Arduino IDE and PlatformIO. Plus, the battery connector faces *outward* so it is incredibly easy to access!

This module has a huge hardware problem - Wifi does not connect unless serial monitor is active in the debugger. This means that wifi can't be used in standalone mode. It can be "worked around" by connecting a 330 ohm resistor from EN to GND but then the serial port is disabled.Also know that the top line is hardcoded yellow where the rest of the display is hardcoded blue. Not a huge issue but it's not a true color display as one might think.

Recomendado

I recently got my hands on the Ideaspark ESP32 Development Board, which comes with an integrated 0.96 inch OLED display, and I am really impressed! The OLED screen is a fantastic addition, providing clear and immediate feedback for my projects, which is especially useful for real-time data monitoring. The board supports WiFi and BLE functionalities, making it extremely versatile for any Arduino or MicroPython applications. The CH340 driver ensures smooth communication, and the pre-soldered pin headers made setup a breeze. The integration of the Micro USB also enhances its convenience. For anyone looking into serious DIY electronics or IoT projects, this board offers great value with its rich features and ease of use. Highly recommended!
