Review on 📡 HiLetgo ESP32 OLED WiFi Kit - Internet Development Board for Arduino ESP8266 NodeMCU with 0.96 Inch Blue OLED Display, WiFi, Bluetooth, and CP2012 by Eric Cortes

First Impression: Nice board with small OLED display. One day I immediately noticed the plastic base on which the OLED sits. The base was tightened with 4 small screws at the back. This makes the board more stable as the position of the OLED doesn't move as easily. The default sketch was a program that ran a Wi-Fi scan, which is nice because you can immediately see that the Wi-Fi module and the display unit are both working properly. This can serve as a test of the functionality of the board. The easiest way to use this board is to use the Arduino IDE. I was particularly interested in the ESP32 touchpads on this board. This is one of the new features that the ESP8266 (the younger brother of the ESP32) doesn't have. I wrote a simple sketch to test one of the touch contacts. It works fine as expected. (According to the pinout, this board has 10 capacitive touch pins. With the exception of the OLED pins, the board has 8 touch pins.) In addition to the above, this board also has a temperature sensor and a hall sensor (ie, all in all it is). this a nice little ESP32 microcontroller board. The built-in OLED display is a plus if you want to see board status. As for me, sometimes I like to use it to display a debug message instead of depending on the serial port. Last but not least, as an advanced user, you can use the Espressif SDK directly to take full control of your board. I highly recommend this board!
