Like I2C and SPI, these UART pins can be mapped to any GPIO pin on the ESP32. However, they have a default pin assignment on most board models. For most ESP32 boards the UART pin assignment is as follows:

There are two power pins: the VIN pin and the 3V3 pin. The VIN pin can be used to directly power the ESP32 and its peripherals, if you have a regulated 5V power supply. The 3V3 pin is the output from the on-board voltage regulator; you can get up to 600mA from it. GND is the ground pin.
