Notes

  • NeoPixel with pin-controlled power; STEMMA QT connector for I2C; Reset and DFU (BOOT0) buttons; On/Charge/User LEDs
  • io.power_out QUOTED: vendor pinouts page states "These pins are the output from the 3.3V regulator, they can supply 500mA peak." (shared ESP32-S3 Feather guide)
  • usb_serial derived from usb.bridge (native) + soc usb.type otg-full-speed + serial-jtag
  • dimensions_mm OMITTED: no board dimensions stated on the product page
  • io.gpio_exposed/gpio_free OMITTED: vendor pinouts page does not print an explicit broken-out GPIO count, so no count is derived
