ESP32-S3 touch display development board standardized on a portrait ILI9341 TFT by default, preserving USB-C power, CP2102N USB-UART, I2C touch, PCM5102A audio, microSD, and expansion while assigning KEY1-KEY5 to BOOT, RESET, USER1, USER2, and USER3. The next design pass is driven by a portrait-oriented board resize and user-facing edge placement of the display area, touch interface, controls, and primary connector access.

A simple voltage divider to showcase how to make parts. A voltage divider is a simple circuit which turns a large voltage into a smaller one. Using just two series resistors and an input voltage, we can create an output voltage that is a fraction of the input. Voltage dividers are one of the most fundamental circuits in electronics.
