Programming and Development

The board supports multiple development environments including Arduino IDE, ESP-IDF, and MicroPython. For Arduino IDE, add the Espressif ESP32 board package URL and install the board definitions via Boards Manager.

Development tools:

  • Arduino IDE (with ESP32 board package)
  • PlatformIO (with lolin32 board ID)
  • ESP-IDF framework
Select "WEMOS LOLIN32" or "LOLIN D32" board in Arduino IDE
The board uses CH340G USBtoserial chip - install driver if needed
The USB port is for programming but may not provide enough power for all peripherals

Troubleshooting

Board not detected:

  • Use a datacapable USB cable (not chargeonly)
  • Install CH340G USB driver
  • Try a different USB port

Upload fails:

  • Hold BOOT button while uploading if board doesn't enter boot mode
  • Check correct board selection in IDE
  • Verify port selection matches connected device
