Notes

  • 8 MB flash, 2 MB PSRAM on the ESP32 PICO-D4 module
  • flash_mb=8 QUOTED: guide states "8 MB of Flash memory". psram_mb=2 QUOTED: guide states "2 MB of PSRAM".
  • Battery input pads on underside with diode protection for external packs up to 6V; no onboard charging. QUOTED: "Battery input pads on underside with diode protection for external battery packs up to 6V input".
  • usb.bridge/usb_serial: this plain-ESP32 board has no native USB, so it flashes over a USB-serial bridge; the pinouts page documents two production variants -- QUOTED "The CH9102F USB to serial converter can handle 50bps to 4Mbps max rate." and "The CP2102N USB to serial converter can handle 3 mbps max rate." Because the fitted chip varies by run, usb_serial is recorded as usb-uart-bridge-unspecified.
  • io.gpio_exposed=11 QUOTED: pinouts page states "There are eleven GPIO pins broken out to pads." (gpio_free omitted -- no vendor-printed free count and not derived here).
  • extras QUOTED: "Built-in RGB NeoPixel LED with power control" and "STEMMA QT plug-n-play connector".
