Built onSparkFun MicroMod ESP32 Processor BoardESP32 SoC

An ESP32-D0WDQ6-V3 processor board in SparkFun's MicroMod form factor: a small M.2-keyed edge-connector module meant to plug into a MicroMod carrier board rather than be used standalone. 16 MB flash, dual-core LX6 up to 240MHz, WiFi + Bluetooth.

Notes

  • ESP32-D0WDQ6-V3; 16 MB flash
  • ESP32-D0WDQ6-V3 chip variant has no PSRAM per Espressif's ESP32 series ordering table
  • M.2-style MicroMod edge connector; requires a MicroMod carrier board (not sold with one). USB is routed through MicroMod connector pads to the carrier board rather than exposed on the processor board itself
  • Onboard status LED and 2.4GHz WiFi/BLE antenna
  • io.gpio_exposed=13 QUOTED: vendor hookup guide states "The MicroMod connector supports a total of 12 general purpose IO pins, 7 of which are used on the ESP32 Processor, on top of the 6 dedicated pins" -- 7 general-purpose + 6 dedicated = 13, summing the two vendor-stated integers directly (no estimation)
  • io.gpio_free intentionally OMITTED: this is a MicroMod M.2-style edge-card processor board with no standalone header -- its pins land on a card-edge connector meant to mate with a separate MicroMod carrier board, not a breadboard-style GPIO header a user can wire into directly. gpio_free presumes a usable header; it does not apply here
