Notes

  • Micro-USB UART-bridge port; bridge chip is CP2102 on v4 (up to 1 Mbps) or CP2102N on v4.1 (up to 3 Mbps) — version-dependent, so usb.bridge left unset
  • Built around the ESP32-PICO-D4 SiP (complete ESP32 system including 4 MB flash); no PSRAM
  • Single red 5V Power-On LED
  • io.gpio_free=19 DERIVED, not quoted (SPEC-io-power.md §5.3). Headers J2+J3 break out all 34 pads on the chip (quoted from the user guide pin tables: J2 = GPIO 1,3,5-10,18,19,21-23,34,35,37,38; J3 = GPIO 0,2,4,11-17,25-27,32,33,36,39). Subtracting esp32's soc.reserved_pins that are exposed -- strapping {0,2,5,12,15} (5), input_only {34,35,36,39} (4), and usb_flash_tied {6,7,8,9,10,11} (6) -- gives 34 - 5 - 4 - 6 = 19. 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-PICO-KIT — 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.
