Notes
- Micro-USB UART-bridge port confirmed; a second, native ESP32-S2 USB OTG interface is also present but its physical connector type is not stated in the guide text (omitted)
- Bridge chip model not named in the official user guide (omitted)
- Recommended build is ESP32-S2-DevKitC-1-N8R2 carrying ESP32-S2-SOLO-2, 8 MB flash, 2 MB PSRAM; other module/flash/PSRAM combinations exist (fixed spec omitted since it varies by SKU)
- Dimensions only in separate PDF/DXF files (omitted)
- io.gpio_free=31 DERIVED, not quoted (SPEC-io-power.md §5.3). Headers J1+J3 break out 36 pads total (quoted from the user guide pin tables: J1 = GPIO 3-18,46; J3 = GPIO 0-2,19-21,33-45). Subtracting esp32-s2's soc.reserved_pins that are exposed -- strapping {0,45,46} (GPIO46 also listed under input_only, so counted once) and usb_flash_tied {19,20} -- 5 unique reserved pins exposed -- gives 36 - 5 = 31. Math not vendor-stated; verify before treating as exact.
