Notes

  • 4 MB flash
  • MCP73831 Li-ion charger IC
  • 8 uA low-power mode current
  • Official BOM lists the exact module ordering code ESP32-WROVER-IE-N4R8 (4 MB flash, 8 MB PSRAM)
  • io.gpio_free=5 DERIVED, not quoted (SPEC-io-power.md §5.3). Vendor free-GPIO page table marks 13 native ESP32-WROVER-IE-N4R8 pins FREE (not tied to internal components): IO2,4,5,12,13,14,15,25,26,34,35,36,39 (note: the page's own TL;DR prose list omits IO4, but the per-pin table marks it FREE -- used the table). Subtracting esp32's reserved_pins that are among those free pads -- strapping {2,5,12,15} (4) and input_only {34,35,36,39} (4) -- gives 13 - 4 - 4 = 5 (remaining: IO4,13,14,25,26). Math not vendor-stated; verify before treating as exact.
