I haven’t inspected the schematic yet, so I can’t confirm the design is electrically correct. No project changes have been made.

A proper review still needs to check ESP32-S2 power/decoupling, EN and boot straps, USB-C/USB data wiring, CH340C UART/auto-programming, AMS1117 stability and thermal margin, protection, connector pinout, and ERC/connectivity. This inspection can’t run because no ACUs are currently available.
