It seams that in some ESP32 board, the I²C bus is not configured properly by default. However, you can set almost any pin on ESP32 to setup I²C capabilities. All you have to do is callWire.begin(SDA, SCL);where SDA and SCL are the ESP32 GPIO pins. See the folder examples...

VIN. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.The all...
Step 1: SChematic The TFT LCD (3.5 inch, 320x480 pixel, ILI9488 LCD controller), is used for this instructable. The LCD is easily interfaced with Arduino SPI bus, and it needs minimum of four Digital IO lines. The ILI9488 LCD Controller is a 16.7M single-chip SoC driver for a-Si ...

As can be seen from Figure 3, the color sensor is connected to the serial Inter-Integrated Circuit (I2C) bus, the LED driver is connected to a digital output pin (0), and the pH sensor is connected to an analog input pin (A1). The I2C is a two-wire bus that includes serial data...
(SCL) to keep the clock. Each I2C connection can have one master and multiple slaves. A master can write to slaves and request the slaves to give data, but no slave can directly write to the master or to another slave. Every slave has a unique address on the bus, and the master ...
CAN Bus is a small-scale networking standard, originally designed for cars and, yes, busses, but is now used for many robotics or sensor networks that need better range and addressing than I2C, and don't have the pins or computational ability to talk on Ethernet. CAN is 2 wire differenti...

but the wiring pinout specifically did not. Their cable schematic had a few apparent inconsistencies. (Example: one end of the cable had two ground pins and the other end did not.) They also had a “Menu” button that I lacked. These may just be the result of different products, but ...
