+# ESP32 Pinout
+
+The model of ESP32 used in this project has a unique pin layout compared to other ESP32 boards, and even with board that have a similar model number.
+The DOIT Devkit V1 normally has a GND (ground) pin directly next to the 3v3 pin (3.3V power), but this board specifically has its CLK (clock cycle) pin directly beside the 3v3 pin.
+
+The layout is as follows, with the board in the center between the two sides.
+Slashes are used to determine specialty use cases for the individual pins.
+For example GIPO4/TOUCH0 would indicate that the pin, although is designed especially for touch events, is also usable as a GPIO pin.

+<p id="note-1">
+Pins SCK/CLK, SDO/SD0, SDI/SD1, SHD/SD2, SWP/SD3, and SCS/CMD, namely, GPIO6 to GPIO11 are connected to the integrated SPI flash on ESP-WROOM-32 and are not recommended for other uses.
