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.

Domains: field 24V I/O, precision analog, logic/Ethernet. Safety behavior: E-stop and valve-disable force all analog command outputs to 0V-safe state and disable field enables; watchdog and power-good supervisor reset MCU on comms or rail faults. PCB constraints: L1/L4 signal+components, L2 solid GND, L3 power plane, 1.0mm board inset margin, RJ45 at edge, field connectors on opposite edge, isolation corridor between field wiring and logic/Ethernet, 4x M4 plated mounting holes inset 10mm from corners.
