Notes

  • 8 MB flash, 2 MB PSRAM
  • CH9102F USB-UART bridge (upgraded from CP2102N as of May 2022)
  • STEMMA QT connector with switchable 3.3V power; mini NeoPixel; user button on pin 38
  • io.gpio_free=13 DERIVED, not quoted (SPEC-io-power.md §5.3). Pinouts page gives explicit GPIO numbers for all 21 header pins (bottom row: GPIO26/25/34/39/36/4/5/19/21/7/8/37; top row: GPIO13/12/27/33/15/32/14/20/22). Subtracting esp32's soc.reserved_pins that are exposed among those 21 -- strapping {5,12,15} (3), input_only {34,36,39} (3), usb_flash_tied {7,8} (2) -- gives 21 - 8 = 13. Math not vendor-stated; verify before treating as exact.
  • io.power_out QUOTED: vendor page states "The regulator can supply 500mA peak but half of that is drawn by the ESP32"
