Notes

  • 4 MB flash (vendor overview: "4MB of flash")
  • psram_mb OMITTED: the vendor page lists flash but does not state any PSRAM, so no value is recorded (absence is neutral, not asserted as zero)
  • LiPoly charging and monitoring with the MAX17048; STEMMA QT I2C port; status NeoPixel; second low-quiescent LDO (vendor cites as low as 17uA deep sleep)
  • io.power_out QUOTED: vendor pinouts page states "These pins are the output from the 3.3V regulator, they can supply 500mA peak."
  • usb_serial derived from usb.bridge (native) + soc usb.type serial-jtag: the ESP32-C6 flashes over its built-in USB Serial/JTAG core, not a UART bridge. Vendor overview: "built in USB Serial core" for debugging only, "cannot run UF2" and cannot act as an HID or mass-storage device
  • dimensions_mm OMITTED: no board dimensions stated on the vendor overview or pinouts pages
  • io.gpio_exposed/gpio_free OMITTED: vendor pinouts page does not print an explicit broken-out GPIO count, so no count is derived
