Notes

  • Two USB Type-C ports: a UART-bridge port and the native ESP32-H2 USB port (USB 2.0 full speed, up to 12 Mbps)
  • Bridge chip model not named in the official user guide (omitted)
  • Carries ESP32-H2-MINI-1 or -1U module, 4 MB flash integrated in the chip package; no PSRAM
  • Addressable RGB LED on GPIO8
  • Dimensions only in a separate Dimensions PDF (omitted)
  • io.gpio_free=14 DERIVED, not quoted (SPEC-io-power.md §5.3). Headers J1+J3 break out all 19 pads on the chip (quoted from the user guide pin tables: J1 = GPIO 0-5,13-14; J3 = GPIO 8-12,22-27). Subtracting esp32-h2's soc.reserved_pins that are exposed -- strapping {8,9,25} (3) and usb_flash_tied {26,27} (2) -- gives 19 - 3 - 2 = 14. Math not vendor-stated; verify before treating as exact.

Verify my board

Reads the connected chip over USB and checks it against what esp-atlas cites for ESP32-H2-DevKitM-1 — over Web Serial, no backend, nothing leaves your browser.

In-browser verify needs Web Serial: Chrome or Edge on a desktop. Safari, Firefox and phones cannot do it.
